Java programming (advice, suggestions needed).

[serengeor]

I started learning java few days ago and started building 2d games. The first was pong, now I'm creating brick breaker game.
You can download it from here:
breakout.jar - 21.5 Kb
The game might be buggy, it's far from finished.

I'm looking for advice on learning java programming (on whole, not just game programming) from some more experienced java developers. If you know some good articles/books please tell.
Also I'd like to ask what common mistakes do beginners make in java?

Maybe try http://mindview.net/Books/TIJ4 .
Btw, I had somewhere very nice Java book about 2D graphics programming, if I find it I will let you know.


edit:
Got it, it's:

Computer Graphics for Java Programmers
Second Edition, Leen Ammeraal, Hogeschool Utrecht, Kang Zhang
University of Texas at Dallas

btw, check your forum mailbox

Well as learning the language...just keep coding. If you can programm any other language is nothing special really. And C++ is really not that far away from Java.
Concept wise its pretty much the same. But interfaces in java are somewhat special. You can do some crazy stuff with them which would take way more time in c++.

cpp Code: Select all

 
interface myinterface {
        public void dostuff();
}
 
public class Test {
       
        public int i;
       
        public static void main(String[] args) {
               
                Test t = new Test();
                t.run();
        }
       
        void run() {
                i = 5;
                func(new myinterface() {
 
                        @Override
                        public void dostuff() {
                                System.out.println("DATA: "+Test.this.i);
                        }
                       
                });
        }
       
        public void func(myinterface i) {
                i.dostuff();
        }
 
}
 

But you probably knew that already. And Generics are basicly templates as you know them from c++.

Edit: Oh and threading is a breeze in java
Besides you should take a look at all the java standard libs

Download?! Piracy?! I am filling now report form to FBI and SOPA.


This is nice and thick book, worth of investing these few dollars in buying one.

Thanks for all responses so far. If you have anything else to say, please

Oh, and yeah.. I forgot that most of you can't read lithuanian, so here's a new link with a bit updated game: http://dl.dropbox.com/u/29244943/breakout.jar

@Sudi: I haven't yet written interfaces myself so far. But they look similar to c++ abstract classes.
And this:

cpp Code: Select all

void run() {
                i = 5;
                func(new myinterface() {
 
                        @Override
                        public void dostuff() {
                                System.out.println("DATA: "+Test.this.i);
                        }
                       
                });
        }

Looks strange a bit, though I understand what it does.

PS. I used this http://pages.cs.wisc.edu/~hasti/cs368/JavaTutorial/ so far, with a combination of samples I found around the net.

Serengeor, sent!

About Lithuania, it remembers me a great poem of Adam Mickiewicz:

Lithuania, my country! You are as good health:
How much one should prize you, he only can tell
Who has lost you. Your beauty and splendour I view
And describe here today, for I long after you.
