Jpanel添加鼠标监听器

Question

部分代码如下，当点击退出系统是弹出退出！窗口，点击退出就关闭当前窗口，怎么实现
JTabbedPane tabbedPane = new JTabbedPane();
JPanel ExitPanel = new JPanel(); //退出面板
ExitPanel.setBackground(Color.white);
ExitPanel.setLayout(new BoxLayout(ExitPanel, BoxLayout.X_AXIS));
if(ExitPanel.equals (" 退出 ")){
JOptionPane.showMessageDialog(null, "退出！");

        System.exit(0);

    }; 
    tabbedPane.addTab("   退出系统   ", null, ExitPanel, " 退出系统   ");


    return tabbedPane;
    }
