I wouldn't worry too much about security and performance of this site in particular in your interactions with CodeRanch.

They are important topics in our industry, but there are people working on those kinds of issues behind the scenes to keep the site working well.

There have been isolated incidents of performance or availability on this site that have been handled fairly quickly, but overall, I have found this site to be both stable, performant and secure.

Unlike some other sites that are also pretty good, this is not being provided primarily to make a lot of money, but to help the community.

There are some advertisements and links, but far fewer than I find on most other sites that I visit for information about Java development.

The infrastructure and management of this site is shared with some other very nice sites that are not primarily related to software development, but share common ownership.

The link that you probably clicked on accidentally (already discussed) showed one of them.

Regarding your other questions about grammars in computer programming, there are large topics covering them.

Lexical software and grammars were well established when I was first studying programming at University in the 1980's.  Two of the many tools that were being used at the time were lexx and yacc.  Yacc stood for "Yet Another Compiler Compiler" and was the most common way for example, a C compiler to be implemented.  The open software community started with one of its first major projects being bsn or bison.  I worked for more than a decade for a company that had our own parsers which were implemented in flex and bison.  Only two or three or at most four of far more than 100 programmers working on our system wrote or ever modified any of that code, the rest of them just used it to build our larger systems enabling our customers to run their businesses.
There are tons of paid and free materials about these subjects which were historically covered in courses on Compilers.

Most people no longer consider these classic tools to be the best choices any more for modern development.

One very popular tool is ANTLR:
https://en.wikipedia.org/wiki/ANTLR

Newer parser-based software at the company I worked at used that, and many like it a lot, but there are also many other choices.

Many programmers have productive careers without ever paying attention to those areas of computer science, but there is a whole large sub-field of parsing and many specialize in these technologies.

More recently, and in my opinion primarily because of the increased availability of large amounts of processing power and ever-increasing integration of computers into all areas of life, the field of natural language processing has received increased attention:
https://en.wikipedia.org/wiki/Natural_language_processing

This again, is a somewhat specialized field, with most programmers not knowing very much about it and not basing their careers on it.  I personally have not had a lot of discussions on these topics here at the Ranch, with the exception of some funny stories about ANTLR.

My guess as to why you did not come across these topics in your studies is that they are generally considered specialized or advanced by most programmers, who are more interested in using the compiler to get their work done and run someone's business than in the computer science behind them.  Most people who have Computer Science degrees will have been exposed to these topics, but relatively very few of them will ever be paid to write a compiler, other parsers, or to be employed using Natural Language Processing.

They are all good things to know, but are likely not to be something that would be good for you to focus on in the interests of attaining gainful employment in the short term.  For that you probably want to focus on somehow finding places that are in need of skills in areas you have demonstrated significant experience or success in, usually with the help of Recruiters, and likely ones that are based in your part of India.  Even though the field has gone global, and I had been contacted by recruiters based in India, UK and other countries, ultimately the ones that led to success were based in my part of the United States, and then determined that my skills and experience matched requirements for positions that were very difficult to fill with "average, usual" programmers with more commonly encountered employment experience.  A good recruiter will learn your strengths and weaknesses and is trained to match you to appropriate positions.  Additionally, they spend all day every day looking at open positions and trying to find appropriate people with backgrounds that would make them a good fit for them.

To my knowledge, there are not many recruiters on CodeRanch, at least not in the forums I spend my time in.
It is important that they can understand you in discussions, when they ask questions such as "What do you consider your strengths and weaknesses?  What roles have you had the most success in on teams?  What do you prefer to spend your time on focused on at work?  What would your co-workers say your biggest strengths and weaknesses are?  Have you ever worked with SpringBoot? etc. etc. etc."  I presume there are a fair number of them within India that might be comfortable conversing in Tamil if you feel more comfortable doing so, but I don't know any to refer you to.

In my opinion, finding local recruiters willing to work with you, getting them to know you and deciding what sorts of positions you would be most likely to do well at, and staying in regular touch with them would be the most productive way to get a job working for someone else, either contracting or full-time.  Self-employment is an option, but as others have explained in other threads, there is a tremendous amount of other work and skills required to be successful in that, not just technical but in obtaining customers and keeping them happy.  I have less experience in that area, I have always worked on larger teams developing large products for large customers all over the globe.  So when I am looking for work, recruiters play a very big role in the search.

Hello All, Thanks for the Opportunity. Sorry for inconvenience If any.
I will look in to the all post & comments again If possible in this Thread.

I studied Higher Secondary Certificate with Mathematics, Computer Science subjects.
I studied Flow chart and Computer Programming in Mathematics, Computer Science.
I thought about Positive Data scenarios & Negative Data scenarios in various data types such as Integer, String, Float, etc.
Similarly in Word star software etc I thought about Positive Data scenarios & Negative Data scenarios .

I think When I was studying Mechanical Engineering, I thought about Negative data in Char data type.

I liked to use more realistic data in programming etc.
Some time I think I was not liking Dummy data or Fake data in programming during school time when I was writing sample programming & Data during school time.
I may faced difficulty to use dummy data or Fake data during school time.

Under negative data I not analysed about Fraud data during school time.

If possible, How to Handle Fake Data, Dummy Data, Fraud data needs to be analysed in Computer Programming, Books, Tutorials etc.
How to Handle Fake Data, Dummy Data, Fraud data scenarios needs to be analysed in Computer Programming Negative data scenarios If possible.
Quality should be improved in Computer Programming If possible.

If possible, only accurate data should be used for Computer Programming

I think I have seen LinkedIn United Nation organization post about Verified Data etc

Industrial Engineering System Modeling and Simulation is also related Realistic Model etc

I hope this thread is related to Positive Data, Negative Data in Java, Database etc
I hope above inputs may help in handling all types data & Quality in Java Programming & Database Development etc

Thank you

There is a term in Database Security topic of "Negative Database":
https://en.wikipedia.org/wiki/Negative_database

I know that in medical research, the issue of Negative Data is a very big one, it is important but I don't think this is how you are using the term:

https://www.ascb.org/careers/positive-spin-power-negative-data/

https://arxiv.org/abs/2102.05113

https://thepublicationplan.com/2021/02/24/overcoming-barriers-to-reporting-negative-data-perspectives-from-the-center-for-biomedical-research-transparencys-founder/

https://www.fusfoundation.org/the-foundation/news-media/blog/the-stigma-of-negative-data-and-how-preprint-servers-can-help

I have friends that are in Research Science, where that issue is extremely important as you can see from those links.

However, it isn't clear to any of us whether it is that issue that you wish to discuss further or there is a difficulty we are having in terminology.

So again, it remains unclear when you are talking about "Positive Data" and "Negative Data" whether you mean the terms as used in Research Science and Medicine, or you merely mean say, numeric quantities greater than or less than zero.

Some of your statements led me to think you were suggesting the meanings we normally would use the terms "Valid Data" and "Invalid Data" for.  Almost nobody, regardless of their first language (English/Tamil/Mandarin/Russian/Portuguese) would use the terms in that way.

This thread has been around for quite some time, and various people are generally up for discussion of a variety of interesting topics, but I am afraid that nobody reading this thread yet has a clear idea of what you mean to describe by your use of the terms "Positive Data" and "Negative Data".

I posed some guesses way back in the thread, and added some new ones now, but those terms are not standard in Computer Science and it remains unclear precisely how you are using them.

Hello Jesse Silverman, Thanks for the Opportunity. Sorry for Inconvenience If any.  
I studied Secondary School Leaving Certificate (SSLC)  before studying Computer Science in Higher Secondary Certificate (HSC).
In SSLC, Mathematics is one of the subject. In Mathematics Graph, Geometry etc are created.
In graph various diagrams are plotted in +X, -X, +Y, -Y axis. One of the graph is Parabola Graph.
Please check about this in Internet If possible

In HSC, Computer Programming is taught under Computer Science, Mathematics.
In HSC, I compared Word star software with Star hotel such as 5 star hotel.
I thought about Words with many stars, words with negative stars If any similar to Star hotel.
I also thought about Synonyms and Antonyms of Words in English for various words when thinking about Word star software.
I also thought about Cinema stars, India Sports stars etc for writing essay in Word star software etc.
I also thought about Words star Words with Dash for Example A _ _ L E (A P P L E) similar to exam questions before SSLC or Competitive examinations
After using Computer, Rarely I see few English words with star in News
I think I have seen few Tamil movies with Dialogues changed with some sound as part of censorship during my childhood time

Computer Programming Integer, Float, Data types directly linked to Mathematics.
Positive & Negative data may picked from Graph +X axis, -X axis, +Y Axis, -Y axis etc.

String data Data type may linked Dictionary words, Non dictionary words etc.
char data type only holds characters like 'A', 'B',..'Z' or 'a', 'b',...'z' .
If I compare Graph, I thought about char data as  '-A', '-B',..'-Z' or '-a', '-b',...'-z' ,  '+A', '+B',..'+Z' or '+a', '+b',...'+z' .

I started to study Graph, Geometry etc from middle school onwards.
In Computer Science & Programming also positive scenario, negative scenario testing etc are done.
Exhaustive cases, testing needs to be performed for various requirements in (Software Development Life Cycle) Water fall model or Agile Model etc in Software Development Life Cycle.
Valid data, invalid data needs to be identified, classified and exception should be thrown in Java for invalid data.
Error data needs to be logged, corrected for quality improvement etc.  
Validation of data is depends up on Business logic or Use case etc.
I shared known knowledge here. Please consider these.
If String data is entered, That String data linked to Auditory, Visual or Feel perceptions. (Reference: I attended one Leadership training in TCS many years before).  
If possible String data needs to be analyzed for data quality If anything possible.
I am using Physical Book Dictionaries, Mobile Dictionary, Online Dictionary etc.
Difficult words, Unknown words etc needs to be analysed carefully with the help of experts, Leaders etc If possible in String data.
More Language Administration skills, More Leadership skills may needed for String data as per my Feel of Tamil Dictionary, English Dictionary etc
If more than one language used in input data, more complexity is involved.
We may need to involve more translators needed in String data handling, Business logic etc.
Global level applications with multiple languages mixed input means we need Translation facility & Resources etc needed for quality verification purpose.
Thank you

Now we are getting somewhere.
The most common use of the terms 'negative' and 'positive' is indeed the same in Computer Science and the other fields you mentioned.
In Java, all numeric types are signed (unless you count Character, which we normally don't, although we are allowed to perform mathematical operations with them too).
So using 'positive' to describe any numeric quantity > 0 and 'negative' to describe any numeric quantity < 0 is very common and will be recognized by all.

Many of us have fond memories of some of the older computer systems, programming languages and software products we have used very long ago.
Occasionally, in relaxed conversation, we will bring them up if, for instance, someone is describing some recent trend or feature as if it was "new", when in fact something we used decades ago did the same thing or better.
WordStar was loved by many, I am going to talk about it a little to help you get it out of your system, and perhaps feel better about your attachment to it, as there are various others who felt the same way, from:
https://en.wikipedia.org/wiki/WordStar

Wikipedia wrote:Notable users
WordStar was the program of choice for conservative intellectual William F. Buckley, Jr.,[30] who used the software to write many works, including his last book. This was noted by his son, Christopher Buckley, who wrote of the almost comical loyalty and affection his father had shown for WordStar, which he had installed into every new computer he purchased despite the technical difficulty of such an endeavor as the program became increasingly outdated and incompatible with newer computers. He said of WordStar, "I'm told there are better programs, but I'm also told there are better alphabets."[30]

Ralph Ellison also used WordStar.[31]

Canadian science fiction author Robert J. Sawyer continues to use WordStar for DOS 7.0 (the final release) to write his novels.[32][33]

A Song of Ice and Fire author George R. R. Martin still (2020) uses the MS-DOS version of WordStar 4.0.[34][35]

Andy Breckman, the creator of Monk, is a devoted WordStar user.[36]

Vampire fiction writer Anne Rice was another faithful user of WordStar who struggled to have it installed on newer computers until it could no longer reasonably be done. She then grudgingly transitioned to Microsoft Word, whose design she felt was comparatively unintuitive and illogical: "WordStar was magnificent. I loved it. It was logical, beautiful, perfect," adding, "Compared to it, MS Word which I use today is pure madness."[37]



Every one of these people is a far, far better writer than myself, and far more people want to read their works.
The ones that still survive might still enjoy talking about WordStar with you.

However, by the time I started Engineering School (in 1985), it had largely been displaced by WordPerfect, and by the time I started working full time as a computer programmer, in 1991, most people thought of it as being relegated to the past, no longer considered a serious competitor to WordPerfect or Microsoft Word.  As mentioned above, some very respectable people strongly disagreed, but the marketplace had spoken.  There are 'fan websites' where some people will talk about how some software packages or hardware platforms or operating systems of the past were better designed than others that have replaced them in a marketplace, we would describe these as 'cult followings', but we will rarely discuss them in a workplace context or on interviews, etc.

Wikipedia wrote:As the market became dominated by the IBM PC and later MS-Windows, this same portable design made it difficult for the program to add new features, and affected its performance. In spite of its great popularity in the early 1980s, these problems allowed WordPerfect to take WordStar's place as the most widely used word processor from 1985 on.

Abandonment
WordStar is no longer developed, maintained or sold by its owners. It is the property of Riverdeep, Inc.[9] There was some uncertainty as to whether Gores Technology Group or Riverdeep now owns WordStar, but the consensus is that it is Riverdeep, an education and consumer software company which is now part of Houghton Mifflin Harcourt Learning Technology.



Many kind people who respond on these threads (at least if questions are being asked that they can understand) are much older, and have many memories of software and hardware systems that were relevant in the 1990's, 1980's, 1970's and in some cases in the 1960's.  They have many colorful stories about those times and those designs that they will sometimes share in relaxed conversations about how much things have changed over the years.

Some of us feel that we are fighting 'ageism' or a tendency to prefer hiring newer, younger, more recent graduates.
I believe some of us have felt that despite being able to talk very knowledgeably about the importance in changes in Java in versions 8, 9, 10, 11 ..l. 17 etc. or the difference in approach to doing, say, websites in Java and different frameworks today versus 20 years ago, and, in fact, knowing just as much about the new versions and choices as any recent graduates.

A tendency for too many of our stories or examples to harken back to 1990 (or even 2010) can contribute to these impressions and make it harder for us to be selected for employment, in an industry that is very often focused on whatever new, shiny, latest buzzwords and trends seem 'hot', whether or not they are actual improvements to older ways of doing things.

I can tell you that I know extremely good developers, with software written by them still being used to run most of the world's largest and most profitable corporations, that are discouraged and feel almost unemployable at this point.  I know that they could still do great development, but for whatever combination of reasons, they feel the world has passed them by, and recruiters/employers seem to agree.

The name WordStar is just a meaningless lexical coincidence compared to other uses of Star in English and in Computer Science.
It could have been called MonkeyHat (and wouldn't be used any less today if it had been).
Thinking about Star ratings of hotels and restaurants and movies is just a coincidence, and not particularly relevant to anything except possibly marketing campaigns from many decades ago.

The Star character, or asterisk is still very important in computer programming.
We use it for multiplication in almost every major popular computer language, tho we normally pronounce that 'times' when saying it allowed.
Additionally, it is used to represent "zero or more of something" in Regular Expressions languages, whereas '?' means either 0 or 1, '+' means 1 or more of something, and the more verbose {3, 7} means exactly 3, 4, 5, 6 or 7 of something we are repeating.

Being very familiar with and handy at Regular Expressions crosses so many tools and programming contexts that it is a very good skill to have indeed.  For whatever reasons, I have been asked Regular Expressions questions on many, many interviews, probably because it provides a quick and easy solution to many problems that are longer and more verbose without their usage.

Since 1.4, Java has had full RegEx support, knowing how to make good use of this will likely be considered a plus by many potential employers.

I would strongly advise you to forget about WordStar and these other uses of star beyond the ones I have mentioned here.
Employers want to know that you understand the subtleties of integer and floating point maths, and how and when to use BigInteger or BigDecimal.  They really, really don't want to hear about WordStar, and you will come off as 'seeing stars' or stuck in the 1980's (I know you used WordStar after most of the world abandoned it, but people who even recognize it think of the 1980's rather than the 1990's when they hear someone referring to it).

So I strongly advise you to leave references to WordStar out of any discussion with potential employers.  The Microsoft Office Suite (or open-sourced equivalents) is a very popular skillset, tho I have not ever had an employer that used the open-sourced alternatives:

https://en.wikipedia.org/wiki/LibreOffice wrote:
2018: The Document Foundation estimated in 2018 that there are 200 million active LibreOffice users worldwide. About 25% of them are students and 10% Linux users (who often automatically receive LibreOffice through their distribution).[183] In comparison, Microsoft Office was used in 2018 by 1.2 billion users.[184]



Many places will use Google Docs and associated software, so being familiar and productive with that is also considered useful.
But for everyone's benefit, I believe you should leave discussion of WordStar to nostalgia forums only.
I won't bring this up again, but thought it was important to address.

You had said something like this before.  No.
The char data type in Java can hold any one of ~65_000 different characters in the Basic Multilingual Plane of Unicode.
Hundreds of thousands of Unicode characters outside of that require two Java characters to represent, this is unfortunate but rarely affects us, as most of the characters we see in business usage (with the exception of emoticons like 💩) lie within the Basic Multilingual Plane.
Many businesses need to support many different spoken and written languages for their customers.
Having a solid background in usage of Unicode for text processing and localization/internationalization is a big plus for them when selecting programmers.  Many otherwise very good programmers have stuck in their minds that everyone speaks, reads and writes English, and write software in a style that makes it very difficult to translate.  There are many aspects of this and quite a number of approaches/patterns and API's that are involved, but these are all important skills to have for making software that is truly internationalized/localized.
There are many great methods in this class:
https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/lang/Character.html

One is https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/lang/Character.html#isLetter(int)

That is true only for some fraction of valid characters, not all characters are letters.  Many are not.

Many programmers don't know nearly as much about Unicode and how to process text in different languages as would be good for those with global customer bases -- I support that if you are passionate about languages, but in discussions even today many programmers I know don't care much about it, they consider the topic exotic and mention it rarely comes up on job interviews they get.

Babu wrote:

While this is something some might consider interesting, I think you should likely forget about this except to remember that Java has both a unary minus and unary plus.  I will show a couple of examples:
jshell> int i = 5
i ==> 5

jshell> int j = -10
j ==> -10

jshell> -i
$6 ==> -5

jshell> +j
$7 ==> -10


I recommend to probably stop thinking about + and - with reference to character data, among other things, character data is unsigned in Java, unlike some other languages.

We have an entire sub-forum on testing, it is a very important topic and too many ignore it.
Data validation is an important topic too, and one that we do discuss here on the Ranch.
Not everyone agrees with the approach of throwing exceptions for invalid data in all cases, but yes, data validation is very important.  There are so many different things you have brought up in this thread, many of which people may have had difficulty understanding, that you have gotten no responses.

Contrast for example this recent thread, where several different people were able to respond with different answers because they understood a particular thing that was being asked:
https://coderanch.com/t/746062/java/Catch

You make many true statements in the big block of text I quoted above.
There are also many other Real World concepts that might be represented by String data -- license plate numbers of cars (we call them license plate numbers despite them containing letters as well, at least we do in the States) Zodiac symbols, names of butterflies or dog breeds or planets or food...it is not clear where we are going with that.
I can't disagree with the sentence "If possible String data needs to be analyzed for data quality If anything possible. " but it is very difficult to know what to do with this.  We aren't playing Jeopardy here, so our answers don't need to be in the form of a question, but our questions indeed do.

Do you begin to see a pattern here?
Many pieces of things that you have posted might have gotten numerous responses, or at least were likely to start some discussion that might be interesting to some, but when all of these ideas are mixed together in a stew, unlike in cooking where as long as our culinary skills can make a popular dish with dozens of flavors in it (this is not a good forum in which to discuss cooking, but many of us are interested in it)...nobody is going to want to eat it.

As I have addressed in this response and others, there are numerous computer science, programming and language skills that are necessary to make consumer software that is truly Globalized.  If one can demonstrate competency in these, it is an advantage when seeking employment.

If you had a question such as "How can I code my Java software to be optimized for internationalization and localization?"  you might have gotten some responses.

Please note (and this is very "meta" as the kids say): when searching CodeRanch for topics about Internationalization or Localization, make sure to also check for 'internationalisation' and 'localisation'.  CodeRanch on the whole prefers American spellings, but many, many of our visitors and staff have British spelling turned on in their brains by default.  I believe that the JavaDocs and the Java Language Specification very much prefer American spellings thru-out.  There are many differences, but the one you will see most commonly is that American words end in -ize and British/Commonwealth countries continue to spell them with -ise, perhaps a holdover of bad feelings from our break-up a few centuries back.

I responded to many different things in this post.  Most people will not.

When you are interviewing in particular, it is very important to them to see that you can be focused and stay on-topic and that you can understand their questions and that they can understand your answers.  This can often be as important or sometimes even more important than your technical competence.

Asking questions that are more "answerable" here at the Ranch might be good practice for that, as has been addressed in the body of this response.
