				package StyleChooser;								import java.awt.*;				import java.awt.event.*;				import javax.swing.JFrame;								public class Frame1 extends JFrame{				     public Frame1(){				        Frame f=new Frame("test");				        f.show();				        f.addWindowListener(new WindowAdapter(){				          public void windowClosing(WindowEvent e){				            System.exit(0);				          }				        });				     }								     public static void main(String[] args) {				      Frame1 frame1 = new Frame1();								    }				}
