java实现简单扫雷游戏

本文实例为大家分享了java实现简单扫雷游戏的具体代码，供大家参考，具体内容如下

package com.test.swing;
 
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
 
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
 
/**
 * 这个是一个简单的扫雷例子，刚接触swing编写的，适合新手练习
 * 该程序使用setBounds（x,y,w,h）对控件布局
 * 做法参考win xp自带的扫雷，当然还写功能没做出来，
 * 另外做出来的功能有些还存在bug
 *
