前言

忘记是从何处看到过关于扫雷小程序的文章，所以这次也就跟着做一下。其实很简单的，如果有java入门的同学也可以尝试一下自己做这种java小程序。几行代码做几遍基本上能摸清楚这些基础了，对于编程能力也能提高一些。（虽然小编玩了半天也才仅仅赢了一把）

具体代码如下：

package saolei;

import java.awt.Color;
import java.awt.Container;
import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Random;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.*;
public class saolei implements ActionListener {
JFrame frame=new JFrame(“扫雷小游戏”);
JButton reset=new JButton(“重来”);
Container container=new Container();

//游戏数据结构
final int row=20;
final in

t col=20;
final int leiCount=30;
JButton [][] buttons=new JButton[row][col];
int [][] counts=new int[row][col];
final int LEICODE=10;

// 构造函数
public saolei(){
//1、设置窗口
frame.setSize(1000, 800);
frame.setResizable(true);
//是否可改变窗口大小
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new BorderLayout());
//2、添加重来按钮
addResetButton();
//添加按钮
addButtons();
//埋雷
addLei();
//添加雷的计算
calcNeiboLei();
frame.setVisible(true);
}
public void addResetButton(){
reset.setBackground(Color.cyan);
reset.setOpaque(true);
reset.addActionListener(this);
frame.add(reset,BorderLayout.NORTH);
}
public void addLei(){
Random rand=new Random();
int randRow,randCol;
for(int i=0;i<leiCount;i++){
randRow=rand.nextInt(row);
randCol=rand.nextInt(col);
if(counts[randRow][randCol]== LEICODE){
i–;
}else{
counts[randRow][randCol]=LEICODE;
//buttons[randRow][randCol].setText(“*”);

}
}
}
public void addButtons(){
frame.add(container,BorderLayout.CENTER);
container.setLayout(new GridLayout(row,col));
for(int i=0;i<row;i++){
for(int j=0;j<col;j++){
JButton button=new JButton();
button.setBackground(Color.orange);
button.setOpaque(true);
button.addActionListener(this);
buttons[i][j]=button;
container.add(button);
}
}
}

for(int i=0;i<row;i++){

counts[i][j]=count;
//buttons[i][j].setText(counts[i][j]+“”);
}
}
}
@Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
JButton button=(JButton)e.getSource();
if(button.equals(reset)){

} return;
}

}
