 源码如下：

package cn;

import javax.swing.*;

public class main {
    public static void main(String[] args) {
        String name = "我是明哥";
        int a = 1;
        while (a == 1) {
            String s = JOptionPane.showInputDialog("请输入我是明哥");
            int r = s.compareTo(name);
            if (r == 0)
                a = 0;
            else
                System.out.println("还想骗我");
        }
        JOptionPane.showMessageDialog(null, "对嘛，你很懂你自己嘛！");
    }
}
