一、效果展示

初级难度

中级难度

高级难度

测试界面

二、项目介绍

项目背景

扫雷是一款大众类的益智小游戏。根据点击格子出现的数字找出所有非雷格子，同时避免踩雷，踩到一个雷即全盘皆输。这款游戏有着很长的历史，从扫雷被开发出来到现在进行了无数次的优化，这款游戏通过简单的玩法，加上一个好看的游戏界面，每一处的细节都体现了扫雷的魅力。

功能分析

完成 难度选择，雷随机生成，数字生成，左右键翻开 等功能实现

游戏四种状态： 难度选择、游戏状态、游戏胜利、游戏失败

游戏难度： 初级、中级、高级（不同难度对应不同的雷区大小和雷数量）

游戏核心： 二维数组 的相关操作

其他： 窗口绘制、界面规划、操作计数、重新开始。

三、代码展示

图形界面设计（gui包）

主类：AppWindows类

AppWindow类负责创建游戏的主窗口，该类含有main方法,程序从该类开始执行。

四、代码测试

这里我们创建test包，实现AppTest类来进行代码的测试，代码如下：

package ch8.test;
import ch8.data.*;
import java.util.Stack;
public class AppTest {
   public static void main(String [] args) {
       Block block[][] = n开发者_自学开发ew Block[5][10];  //雷区
       for(int i=0;i<block.length;i++) {   
           for(int j = 0;j<block[i].length;j++) {
             block[i][j] = new Block();
           }
       }
       LayMines layMines = new LayMines();                        //布雷者
       PeopleScoutMine peopleScoutMine  = new PeopleScoutMine();  //扫雷者
       layMines.layMinesForBlock(block,10); //在雷区布雷
       System.out.println("雷区情况:");
       intputShow(block);
       peopleScoutMine.setBlock(block,10);  //准备扫雷 
       Stack<Block> stack = peopleScoutMine.getNoMineAroundBlock(block[0][0]);//扫雷
       if(block[0][0].isMine()){
          System.out.println("我的天啊，踩着地雷了啊");
          return;
       }
       System.out.println("扫雷情况:");
       intputProcess(block,stack);
       System.out.println("成功了吗:"+peopleScoutMine.verifyWin());
       if(block[3][3].isMine()){
          System.out.println("我的天啊，踩着地雷了啊");
          return;
       }
       stack = peopleScoutMine.getNoMineAroundBlock(block[3][3]);//扫雷
       System.out.println("扫雷情况:");
       intputProcess(block,stack);
       System.out.println("成功了吗:"+peopleScoutMine.verifyWin());
   }
   static void intputProcess(Block [][] block,Stack<Block> stack){
       int k = 0;
       for(int i=0;i<block.length;i++) {
           for(int j = 0;j<block[i].length;j++){
              if(!stack.contains(block[i][j])&&block[i][j].getIsOpen()==false){
                 System.out.printf("%2s","■ "); //输出■表示未挖开方块
              }
              else {
                 int m = block[i][j].getAroundMineNumber();//显示周围雷的数目
                 System.out.printf("%2s","□"+m);
              }
           }
           System.out.println();
       }  
   }
   static void intputShow(Block [][] block){
       int k = 0;
       for(int i=0;i<block.length;i++) {
           for(int j = 0;j<block[i].length;j++){
              if(block[i][j].isMine()){
                 System.out.printf("%2s","#"); //输出#表示是地雷
              }
              else {
                 int m = block[i][j].getAroundMineNumber();//显示周围雷的数目
                 System.out.printf("%2s",m);
              }
           }
           System.out.println();
       }  
   }
}

五、项目结构

六、设计总结

本次项目设计是通过 Java语言编制一个扫雷游戏，Java语言是当今较为流行的网络编程语言，它具有面向对象、跨平台、分布应用等特点。这次设计，还有利于加深对 Java课程的进一步了解，也可以巩固所学 Java语言基本知识，增进 Java语言编辑基本功，拓宽常用类库的应用。采用面向对象思想的程序，锻炼了面向对象的设计能力，使编程者通过该教学环节与手段，把所学课程及相关知识加以融会贯通，全面掌握 Java语言的编程思想及面向对象程序设计的方法。
