FRUSTRATED! Need help, please!

Question

I have written a program for my Pacman maze (see code below).
The program compiles and displays the maze, but the problem is when I minimize the window and miximize it again, the display disappears or becomes corrupted. I thought I need to use repaint or update. HOWEVER this is where it gets interesting. When I have any kind of loop in my paint() method, for example the nested "for" loop in the code below which paints the maze on the screen based on the "board" array, each time I resize or minimize the window, the display becomes corrupted. BUT, if I take the loops out and just use any draw statement to paint something on the screen, I dont have the same problem. And the program repaints the screen perfectly when the window is resized or minimized.
Please help me, I have already spent a long time on this problem.
THanks in advance.
here is the code.
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class Maze extends JFrame
     static int board[][] = { {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
                                   {1,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,1},
                                   {1,0,1,1,0,1,1,1,0,1,0,1,1,1,0,1,1,0,1},
                                   {1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
                                   {1,0,1,1,0,1,0,1,1,1,1,1,0,1,0,1,1,0,1},
                                   {1,0,0,0,0,1,0,0,0,1,0,0,0,1,0,0,0,0,1},

     int count1 = 0;
     int count2 = 0;
     int xbound = 25;
     int ybound = 50;
     public Maze()
          super ("PacMan Maze");
          setSize(800,800);
          show();
     public void paint (Graphics g)
          for(count1=0; count1 < 19; count1++)
               for(count2=0; count2 < 19; count2++)
                    switch (board[count1][count2])
                         case 0:
                              g.setColor(Color.blue);
                              g.fillRect(xbound,ybound,35,35);
                         break;
                         case 1:
                              g.setColor(Color.white);
                              g.fillRect(xbound,ybound,35,35);
                              g.setColor(Color.blue);
                              g.drawRect(xbound,ybound,35,35);
                         break;
                         xbound = xbound + 35;     
          ybound = ybound + 35;
          xbound = 25;
     public static void main (String args[])
          Maze app = new Maze();
          app.addWindowListener(
               new WindowAdapter() {
                    public void windowClosing( WindowEvent e)
                         System.exit(0);
}

Answer 1

I think you did not reset the xbound/ybound variables after the paint, therefore the numbers keep increasing each time the paint method is called.
Try setting both variables to 0 at the start of the paint method.
