        pane=getContentPane();

          pane.add(panel);
   image.addMouseListener(new MouseAdapter()

      public void mouseClicked(MouseEvent e){
           if (e.getSource()==image){
      pane.removeAll();
      pane.add(tabbed);
      pane.revalidate();
      pane.repaint();
           }

       }

   }

   );
    }

    public static void main(String[] args) {
 hotels mw=new hotels();
  mw.setVisible(true);
  mw.setSize(300, 400);

    }

    }

我想在JTabbedPane的右上角添加按钮和标签。

您可以通过适当布局嵌套Container来将Components添加到JTabbedPane之上。例如，要将JLabel和JButton放置在JTabbedPane的上方和右上方，您可以在添加了JTabbedPane的mouseClicked实现中使用BoxLayout:

pane.removeAll();
Box vert = Box.createVerticalBox();
Box top = Box.createHorizontalBox();
top.add(Box.createHorizontalGlue());
top.add(new JLabel("Top Label"));
top.add(new JButton("Top Button"));
vert.add(top);
vert.add(tabbed);
pane.add(vert);
....

您的要求不明确，因此您可能不得不使用背景颜色和边框位置(例如，将边框添加到vert而不是tabbed)来满足您的要求。
