import java.applet.*;
import javax.swing.*;
public class PopUpMenu extends JPanel implements ActionListener{
PopupMenu popup;

public PopUpMenu(){
MenuItem mi;
popup=new PopupMenu("Edit");
mi=new MenuItem("Cut");
mi.addActionListener(this);
popup.add(mi);

mi=new MenuItem("Copy");
mi.addActionListener(this);
popup.add(mi);
add(popup);
enableEvents(AWTEvent.MOUSE_EVENT_MASK);
resize(200,200);
}
public void processMouseEvent(MouseEvent e){
if(e.isPopupTrigger()){
popup.show(e.getComponent(),e.getX(),e.getY());
}
super.processMouseEvent(e);
}
public void actionPerformed(ActionEvent e){
String command=e.getActionCommand();
if (command.equals("Cut")){
JOptionPane.showMessageDialog(null,"CUT");
}
}
public static void main(String args[]){
JFrame frame=new JFrame();

frame.getContentPane().add(new PopUpMenu(),BorderLayout.CENTER);
frame.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e){
System.exit(0);
}
});
frame.pack();
frame.setVisible(true);
frame.setSize(300,300);
}

}
