import java.awt.*;
import java.awt.event.*;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.Random;
import javax.swing.*;
public class DrawJPanel extends JPanel
   // Random object to create random numbers
   private Random randomNumber = new Random();
   // Timer object to generate events
   private Timer drawTimer;
   // ArrayList object to hold MyRectangle objects
   private ArrayList rectangleArrayList = new ArrayList();
   // array of possible MyRectangle colors
   private Color[] colors = { Color.BLUE, Color.ORANGE, Color.PINK,
      Color.CYAN, Color.MAGENTA, Color.YELLOW, Color.BLACK,
      Color.WHITE, Color.RED, Color.GREEN };

   public DrawJPanel()
      super();
      drawTimer = new Timer( 250,
         new ActionListener() // anonymous inner class
            // event handler called every 250 microseconds
            public void actionPerformed( ActionEvent event )
               drawTimerActionPerformed();  
         } // end anonymous inner class
      ); // end call to new Timer
      drawTimer.start(); // start timer
   }  // end contructor
   // create new MyRectangle object and add it to rectangleArrayList
   private void drawTimerActionPerformed()
      // get random dimensions and a random color
      int x = randomNumber.nextInt( 380 );
      int y = randomNumber.nextInt( 380 );
      int width = randomNumber.nextInt( 150 );
      int height = randomNumber.nextInt( 150 );
      int color = randomNumber.nextInt( 10 );
      // create MyRectangle object and add it to rectangleArrayList
      MyRectangle rectangle = new MyRectangle(x,y,width,height,colors[color]);
      rectangleArrayList.add( rectangle );
      repaint();
   } // end method drawTimerActionPerformed
   // draw all rectangles
   public void paintComponent( Graphics g )
      super.paintComponent( g );
      // create iterator
      Iterator rectangleIterator = rectangleArrayList.iterator();
      MyRectangle currentRectangle; // create MyRectangle
      // iterate through ArrayList and draw all MyRectangles
      while ( rectangleIterator.hasNext() )
         currentRectangle =
            ( MyRectangle ) rectangleIterator.next();
         currentRectangle.draw( g ); // draw rectangle
   } // end method paintComponent
   // clear rectangleArray
   public void clear()
      rectangleArrayList.clear(); // clear ArrayList
      repaint(); // repaint JPanel
   } // end method clear
} // end class DrawJPanel

And...?
MyRectangle is not part of the Java API. So that means you wrote it... or something like that. Did you write a MyRectangle class?
