public MyFrame()

setTitle("Super File Cutter");

setLocation(900,400);

setSize(900,900);

final MyPanel panel = new MyPanel();

add(panel);

}

}

class MyPanel extends JPanel

{

public MyPanel()

{

JTabbedPane tab = new JTabbedPane(JTabbedPane.TOP);//标签页容器

Panel p1=new Panel(new GridLayout(5,5));

Panel p2=new Panel();

p1.setName("File Cutter");

tab.add(p1);

tab.add(p2);

}

}

我的代码为什么没有加进来选项卡？
