Default Source Code: Guess the Number Game
This is a simple guess the number game that I though I should do since I just began Java. Then I kept changing it and now the code has a lot of code that new beginners can see and learn from. Atleast I think so. So here it is:
(if anyone doesnt understand my code or has a better way [im not that great, just started] to do something that i did, please feel free to reply)

(It might help to see the code better if you copy code into your complier)
Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;


public cl*** GuessNumber implements ActionListener	{
	private final double VERSION = 2.1;
	//Initializing Main Window and Difficulty Window
	JFrame window = new JFrame("Guess The Number " + VERSION);
	JFrame DiffFrame = new JFrame("Difficulty");
	
	//Making Buttons
	JButton btnNewGame = new JButton("New Game");
	JButton btnInstruction = new JButton("Instructions");
	JButton btnDifficulty = new JButton("Change Difficulty");
	JButton btnAbout = new JButton("About");
	JButton btnExit = new JButton("Exit");

I'm not sure I'll ever have a use for it, but the code is very well written nonetheless.
