Believe it or not, most applications are not consumer products. And even though it may be prevelant in the office with cubicles, most people don't run their companies on microsoft office.

Most applications are doing their work in the data centers, never to be seen by consumers, and only seen my a handful of employees, as backend systems are generally hidden by front end systems.

Can you give me a couple of examples, so that I may ask followup questions?

OK.

Henceforth, I will effort to elucidate in the King's English.

I am just a beginner, looking to get in Software Development as a Profession.

I am trying to get a handle on what Java Professionals are writing. I am so new that I don't even know the categories yet. Let me toss a couple out there and let me know if you are building something in those categories, or if there is another category I need to add.



- Internal Business Apps - Web Based on Oracle
- External B2B Apps - Web Based on Oracle
- External Consumer Facing apps Web - Based on Oracle.

- Any of the above on different DBMS.


If you are a Professional, what are businesses paying you to do?

So apps thru a browser are typically Java.


Apps not thru a browser are typically c++ ./NET.


My research shows that Java jobs are about 3:2 more avail than c++ jobs. Are the "thru a browser" apps a large enough percentage of Business apps that would support the 3:2 number? If not, what are those 3:2 developers writing?

I am starting to learn Java in preparation to get a software engineering job. I researched the jobs available and talked to people in the industry and they say that Java and J2EE are the disciplines in most demand.


I am a few months into learning things, and I am starting to wonder exactly what software Jave builders build. I realize that most jobs AREN'T making consumer software, but B2B software, but the software I see as a consumer are the only frame of reference I have. And the things I see are:


- Consumer Apps I buy at BestBuy like Word or smaller Apps.
- Games I buy at BestBuy.
- Apps I buy thru download, like Thunderbird or Avira.
- Applications I use thru a browser, like Bank of America online banking, or Ticketmaster.
- Games I play on a browser like AddictingGames or Evony.
- Games I play on wii and xbox
- Apps I use on my Iphone.


My question is simply, which of those are typically written in Java. Not could be written, TYPICALLY are written.

And my 2nd question is for those that aren't written in Java, what ARE those written in.

My 3rd and final question is, for those in the above that ARE written in Java, what OTHER languages/tools are needed to be known/used to get them in the form which is a finished product.



I appreciate your answers. Thank you.

I am a few weeks into a career change to Software Engineer and I am trying to figure out what the jobs actually are behind the job listings.

Java is about the largest keyword hit on Software Engineering jobs, but what do these jobs do?


Are they building internal programs or programs that customers would see?

Are they building applications or applets?



I realize that these jobs span all combinations, but where are the bulk of the jobs?


I just figured out that they aren't building smartphone apps, as things like the Iphone require non-java languages/Dkits.



So what do most Java jobs do?

I have installed Notepad++

How do I link N++ to the default of Java source code so that I can click and open with N++ ?

Thank you

Whoopsie.

Thank you very much. Works fine.


Sorry to be THIS stupid. I am sure none of you did anything like this in the beginning.

things that are available from shells in Linux, like repeat last command, finish command, that sort of thing.

Just getting started. I got the following:

C:\Jplan>javac hello.java

C:\Jplan>java hello.java
Exception in thread "main" java.lang.NoClassDefFoundError: hello/java
Caused by: java.lang.ClassNotFoundException: hello.java
at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
at java.lang.ClassLoader.loadClass(ClassLoader.java:303)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:316)
Could not find the main class: hello.java. Program will exit.


So I can compile, but not execute.

The startup at the Cattle Drive indicates that I need to set my CLASSPATH to

.;C\Jplan

I believe I have.

Although I don't know how to check that.

Thanks in advance for the help.


Program is


public class hello
{
public static void main( String[] args )
{
System.out.println("hello world!");
}
}


located in c:\Jplan\hello.java

OK.

Then is there a way to make the command line interpreter a little smarter?

Also,
I see a lot of examples copied from some editor that numbers lines, what is that?

14 years ago
What would you suggest for editor et al for a complete newb to Java?

Should I still be running from the command window?

Any other tools I should acquire?

14 years ago
Thank you.

I am new here and want to follow forum ettiquette.

However I also searched and this was a very close question to mine, minus my specifics.

I shall however not threadjack in the future.

Thank you for the response.

I have found out cut and paste

using right button menu MARK, and ENTER and right button menu paste.

If there are keyboard shortcuts, please post.

Thanks

I am no longer having this problem for reasons unknown.

I can now find the compiler. I am having more problems, but let me see if I can resolve them myself.

Thanks for now.


I still would like to know how to cut/paste to/from command window.

Thanks
