第三个JAVA文件.

import javax.swing.JButton;
import java.awt.*;

public class MineButton extends JButton {
private int row;
private int col;
private boolean cleared=false;
private int countOfSurroundMines;//周围地雷数，如果本按钮是雷，则为-1；

public MineButton(int row,int col){
this.row=row;
this.col=col;
this.setMargin(new Insets(0,0,0,0));
}

public int getCol() {
return col;
}

public int getRow() {
return row;
}

public boolean isCleared() {
return cleared;
}

public void setCleared(boolean cleared) {
this.cleared = cleared;
}

public int getCountOfSurroundMines() {
return countOfSurroundMines;
}

public void setCountOfSurroundMines(int countOfSurroundMines) {
this.countOfSurroundMines = countOfSurroundMines;
}

}

全部编译以后就可以执行了

Answer 2

public int time=1000* 60; //60秒倒计时
public boolean running=true;//是否一直运行
JLabel label=new JLable();//显示时间的标签

//启动计时
public void startTimer(){
new java.lang.Thread(new Runnable(){
public void run(){
while(running){
try{
Thread.sleep(1000);//睡一秒
}catch(Exception e){}
time--;
lable.setText(String.valueof(time));
this.update();// 把你的界面刷新一下
if(time<0){//倒计时到零，满足条件
//your code： 游戏失败，做点处理
running=false;//记得置成false否则不退出
}
}
}
}).start();
}

使用时，在你需要使用的时候 调用 startTimer()方法即可
你可以看到， startTimer方法里的线程在不断地改变time的值，每秒减一
所以你需要在你的GUI界面上安装一个 JLabel label，不断地改变label的内容为time就行了
