Button b=new Button("CENTER");
//BorderLayout
add(lab1,BorderLayout.NORTH);
add(lab2,BorderLayout.SOUTH);
add(lab3,BorderLayout.EAST);
add(lab4,BorderLayout.WEST);
add(b,BorderLayout.CENTER);
}
public static void main(String arg[])
{
myfrm frm=new
myfrm();
frm.setSize(700,400);
frm.setVisible(true);
frm.setLocation(100,10);
}
}
