you can also use AWT. Java has two GUI packages. Swing generally being preferred over AWT.

I've always used JFrame, so never heard of others.

simple program that allows you to move a square around a 10 x 10 map. it's about 200 lines of code so i didn't post it here. don't be scared though, 60 lines of the 200 are just keyboard action events. you'll need to download the images and put them in the same directory as the source.

Needs compiling, right?

I thought that that random number generator was weak and made a new one, much more attractive. Attached is a .jar file and here is a screenshot and the code:



// Imports
import javax.swing.*;
import java.util.Random;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class Main {
    public static void main(String[] args) {
JFrame frame= new JFrame("Random Number generator");
                JPanel panel=new JPanel();
                final Random generator = new Random();
                final int randomNumber = generator.nextInt();
                final JTextArea textArea = new JTextArea(""+randomNumber,5,20);
                JLabel title = new JLabel("Random Number generator");
                JLabel empty = new JLabel("                                   "
                        + "                     "
                        + "                  ");
                JLabel programBy = new JLabel("                                                               by David Gomes");

                JButton generate = new JButton("Generate");
                generate.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent ev) {
                    final Random generator = new Random();
                    final int randomNumber = generator.nextInt();
                    textArea.setText(""+randomNumber);
                }
                });

                JButton quitButton = new JButton("Quit");

                quitButton.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent ev) {
                    System.exit(1);
                }
                });
               

               

                frame.add(panel);
                panel.add(title);
               
                panel.add(textArea);
                panel.add(generate);
                panel.add(quitButton);
                panel.add(empty);
                panel.add(programBy);
                frame.setSize(300,220);
                frame.setVisible(true);
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);;
    }
}
Tell me what you think of it

awesome! I'm keep learning...

Do you like Java?

Yes, I do.
In fact I'm learning it right now(APCS)

That's great. Thanks for waking up this post

I love everything about Java, except that the source is VERY insecure.

you can always just bundle everything up in a couple meaningless wrapper classes, have one-letter var names, method names and classes. and make all your classes implement random interfaces completely off-base to their real purpose. define a final constant True as 0, and False as 1. write comments that lie. of course this really just bloats your code and makes it unmaintainable.. BUT, no one's going to pick through it.

True, or you could write classes that are like the programs that read their own source code, but instead, they decrypt themselves into a program that compiles the real program that then runs. It only takes 10 days to run a hello world program, but hey, it's secure, right? ;-)

But seriously, Java has it's uses and I like it for quite a few things. The fact that I can always get the source of a jar file within two clicks is one of them.
