Hey guys!! I submitted an assignment to cattle drive a week ago and haven't received a response yet. I'm sort of assuming that my nitpicker is just on vacation but I wanted to make sure that it was at least received.

I am working on creating some very basic projects for github and wanted to use HTML and Java together. I'm creating a very basic form where a user can input some text, and the java will spit it back out in piglatin. I know the Java part. I know the HTML part. I don't know how to put them together. I asked a friend and he said JSP ... but that it's been some time since working with Java and there may be a newer technology out there now. So is JSP the way to go here?

Thanks!!

Thanks Jeanne! I'm surprised some companies won't hire entry level over 25 .. that's kinda crazy. If I'm willing to work for entry level wages then why not? I'm actually more than willing to take a paid internship but I don't know that old people like me qualify for them.

And you're right that I do know some people who can at least get me interviews.

Your post gives me hope that I can do this! Even if it's not right now.

As an interviewer ... do you have any recommendations on what looks impressive on github?

Huh? 7 % 10 does equal 7.



Yeah ... please refer to the last part where I said I miss obvious things ... and have trouble understanding the easiest stuff. I swear I'm really not a moron. :P

The "7/10" is not the test. It is the "7 % 10 == 7" that is the test. The test is passed, and the 7/10 equals zero which is sent to the next recursion call. This zero causes the recursion to stop, and the whole thing is unrolled.



I mis-typed this. 7%10==7 ... the remainder of 7/10 is 7. But it's not! So the test isn't passed! That's why I'm confused. Obviously something very obvious just isn't clicking. It's always the easiest stuff that I have the hardest time understanding. :P

Hey guys!! I just reached the recursion section of the coding bat website! Yay! I don't recall every encountering anything like this before so it's taking me a bit to really grasp it. Anyway ... in the screen shot below ... I actually looked up the answer. But when I go through it I don't understand why it works. I DO understand the basics of recursion but I'll explain my confusion.

So in this example ... if n were 717 like the first example I understand the first time it checks it picks up that end 7 and then n is 71. The next round through it just divides by 10 since the remainder isn't 7. Then the number is just 7. So my confusion is ... how does it get that final 7? 7/10 doesn't give a remainder of 7 so how does it know to count that? So obviously I am missing something here.

Thanks!!

Screen shot won't work so I am just copying and pasting the problem and solution.

Given a non-negative int n, return the count of the occurrences of 7 as a digit, so for example 717 yields 2. (no loops). Note that mod (%) by 10 yields the rightmost digit (126 % 10 is 6), while divide (/) by 10 removes the rightmost digit (126 / 10 is 12).

public int count7(int n) {
if (n==0) return 0;

if (n%10 == 7) return 1 + count7(n/10);

return count7(n/10);
}

Thanks Jeanne! This takes me back to my original question ... at this point in time should I seek other employment while I continue to study? I will look into UI and I plan to continue to study java but is a job in this field so far off that I need to find some other type of employment? I've never done more than some freelance work 10 years ago in the development field so I just don't know how much an entry level programmer is supposed to know.

Thanks Jayesh! I will look into that.

I should note that i DO know the answers to questions 2 and 4 but not the other 3, without looking it up.

I started reading one of the training guides for the certification exam but was having a lot of difficulty. I would read it and feel like I understood it ... and then fail the end of chapter quizzes quite dramatically. It was getting really frustrating so I set out to get some real java practice instead (I learn by doing, not by just reading). That's where I found codingbat.com and went through the entire site (almost done). And I know it's basic java ... but it doesn't teach me things like hashmap and the difference between new and literal strings. I might KNOW that ... but I don't know the appropriate vocabulary. Does that make sense at all??

I have not tried creating anything myself. I'd be happy to take suggestions as to what to create that may be a good beginner project.

I would also LOVE a book that comes with explanations AND then quizzes your understanding of that information by making you code stuff. That is absolutely a book that would be perfect for me if you happen to know of one.

Bear - my javascript was never my strongest language. I was much better at ASP and PHP. And while I've not really written anything from scratch in HTML or CSS recently ... I did have to edit the backend of my photography website relatively frequently and that's what was used.

Jayesh - Here's the types of questions I struggle to answer (I am copying and pasting from another website):

1. Which two method you need to implement for key Object in HashMap ?
2. What is immutable object? Can you write immutable object?
3. What is the difference between creating String as new() and literal?
4. What is difference between StringBuffer and StringBuilder in Java ?
9. What is the difference between factory and abstract factory pattern?

This is the kind of stuff that comes up, over and over, when I google "java interview questions." So do you disagree that these are the types of questions that are asked?

I really hope someone can give me some advice here.

Here's my situation. I am a 34 year old woman with a degree in multimedia (focus on web development) from 12 years ago (IOW, it's relatively useless). I've been a stay at home mom and photographer for the past 8 years. I ran my own semi-successful business. But I want out so for the past several months I've been studying java. When I was in school I never studied java. My focuses were on HTML, ASP, PHP, javascript ... all web development languages. At this point I've made my way almost entirely through the coding bat website successfully and I consider myself to have beginner knowledge and I'd really like to get a job. I have no delusions that I'll get anything other than entry level.

But here's the problem ... despite my beginner coding knowledge ... I read those "java interview questions" websites that I've found and I know the answers to almost none of them. They are all theory questions. More like vocab and crap like that. This is really not my strong suit. So I'm not sure I would ever get hired. I've tried studying that stuff, and I will continue to, but it takes my little brain a LOT longer to absorb that sort of boring information than it does the actual code. I pick it up, I understand it, and 10 minutes later I forget it. I'm just not interested. And apparently I forget everything I don't care about.

SO the question is ... should I go for those entry level java jobs anyway? Or should I try to find another part time job and continue to develop my skills and get certified? Do you think, at this point, that I am at all hirable? I CAN answer all of the beginner programming interview type questions ... just not the theory ones.

Thanks!!!

Hey Campbell! Thanks for replying! I will do a search for that. I am studying for is the Oracle Certified Associate Java SE 8 Programmer Exam … and I'm using the official study guide here:

http://www.amazon.com/gp/product/B00R04DF3I?psc=1&redirect=true&ref_=oh_aui_d_detailpage_o01_

I'm not signed up yet. I figured I would sign up when I'm ready.
