jp = (JPanel)getContentPane();
jp.setLayout(new BorderLayout());
jp.add(jpy,BorderLayout.EAST);
jp.add(jpx,BorderLayout.SOUTH);
setBounds(150,150,450,200);
setVisible(true);
}
public static void main(String[] args) {
// TODO Auto-generated method stub
new BoxLayout1();
}
}
为什么会有执行错误说setVisible(true);
有错误.请指点.
