/* * NOTE: This file does not require debugging * */

package debugmeone;

import javax.swing.JFrame;

public class DrawMe extends JFrame { public static void main( String args[] ) { // create frame for CirclesJPanel JFrame frame = new JFrame( "Draw Me" ); frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );

DrawMePanel circlesJPanel = new DrawMePanel(); frame.add( circlesJPanel ); // add circlesJPanel to frame frame.setSize( 200, 250 ); // set frame size frame.setVisible( true ); // display frame } // end main }

///////////////////Here is the code that needs debugging

/* * NOTE: This file requires debugging. In order for Java to draw on your * screen, it calls a very important method. You would seldom call this * method but Java will call it every time it needs to draw your graphics. * * This small program draws 8 circles on a JPanel each of larger size as * it loops. Add the method required to draw the circles on the JPanel. */ package debugmeone;

import java.awt.Graphics; import javax.swing.JPanel;

public class DrawMePanel extends JPanel { for ( int topLeft = 0; topLeft < 80; topLeft += 10 ) { int radius = 160 - ( topLeft * 2 ); g.drawArc( topLeft + 10, topLeft + 25, radius, radius, 0, 360 ); } // end for }
