        Frame frame=new Frame();
        frame.setSize(400,300);
        frame.setLocation(300,400);
        frame.setBackground(Color.black);
        frame.setVisible(true);
        frame.setLayout(new GridLayout(2,1));
 
        //四个面板
        Panel p1=new Panel(new BorderLayout());
        Panel p2=new Panel(new GridLayout(2,1));
        Panel p3=new Panel(new BorderLayout());
        Panel p4=new Panel(new GridLayout(2,2));
 
        p1.add(new Button("East-1"),BorderLayout.EAST);
        p1.add(new Button("West-1"),BorderLayout.WEST);
        p2.add(new Button("p2-btn-1"));
        p2.add(new Button("p2-btn-2"));
        p1.add(p2,BorderLayout.CENTER);
 
 
 
        p3.add(new Button("East-2"),BorderLayout.EAST);
        p3.add(new Button("West-2"),BorderLayout.WEST);
        for(int i=0;i<4;i++){
            p4.add(new Button("for-"+i));
        }
        p3.add(p4,BorderLayout.CENTER);
        frame.add(p1);
        frame.add(p3);
