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。

package ch8.gui;
import java.awt.*;
import javax.swing.*;
import javax.swing.event.*;
import java.awt.event.*;
import ch8.view.MineArea;
import ch8.view.ShowRecord;
public class AppWindow extends JFrame implements MenuListener,ActionListener{JMenuBar bar;JMenu fileMenu;JMenu gradeOne,gradeTwo,gradeThree;//扫雷级别JMenuItem gradeOneList,gradeTwoList,gradeThreeList;//初，中，高级英雄榜MineArea mineArea=null;                //扫雷区域ShowRecord showHeroRecord=null;        //查看英雄榜public AppWindow(){bar=new JMenuBar();fileMenu=new JMenu("扫雷游戏");gradeOne=new JMenu("初级");gradeTwo=new JMenu("中级");gradeThree=new JMenu("高级");gradeOneList=new JMenuItem("初级英雄榜");gradeTwoList=new JMenuItem("中级英雄榜");gradeThreeList=new JMenuItem("高级英雄榜");gradeOne.add(gradeOneList);gradeTwo.add(gradeTwoList);gradeThree.add(gradeThreeList);fileMenu.add(gradeOne);fileMenu.add(gradeTwo);fileMenu.add(gradeThree);bar.add(fileMenu);setJMenuBar(bar);gradeOne.addMenuListener(this);gradeTwo.addMenuListener(this);gradeThree.addMenuListener(this);gradeOneList.addActionListener(this);gradeTwoList.addActionListener(this);gradeThreeList.addActionListener(this);mineArea=new MineArea(9,9,10,gradeOne.getText());//创建初级扫雷区add(mineArea,BorderLayout.CENTER);showHeroRecord=new ShowRecord();setBounds(300,100,500,450);setVisible(true);setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);validate();}public void menuSelected(MenuEvent e){if(e.getSource()==gradeOne){mineArea.initMineArea(9,9,10,gradeOne.getText());validate(); } else if(e.getSource()==gradeTwo){mineArea.initMineArea(16,16,40,gradeTwo.getText());validate();} else if(e.getSource()==gradeThree){mineArea.initMineArea(22,30,99,gradeThree.getText());validate();}}public void menuCanceled(MenuEvent e){}public void menuDeselected(MenuEvent e){}public void actionPerformed(ActionEvent e){if(e.getSource()==gradeOneList){showHeroRecord.setGrade(gradeOne.getText());showHeroRecord.showRecord();}else if(e.getSource()==gradeTwoList){showHeroRecord.setGrade(gradeTwo.getText());showHeroRecord.showRecord();}else if(e.getSource()==gradeThreeList){showHeroRecord.setGrade(gradeThree.getText());showHeroRecord.showRecord();}}public static void main(String args[]){new AppWindow();}

} 

PlayMusic类

package ch8.view;
import java.net.URI;
import java.net.URL;
import java.io.File;
import java.applet.Applet;
import java.applet.AudioClip;
public class PlayMusic implements Runnable {String musicName;Thread threadPlay;AudioClip clip = null;public PlayMusic(){threadPlay = new Thread(this);}public void run() {clip.play(); }public void playMusic(){threadPlay = new Thread(this);try{threadPlay.start();}catch(Exception exp) {}    }public void setClipFile(String name){musicName = name;if(musicName == null)musicName = "扫雷图像/mine.wav";File file=new File(musicName);try { URI uri=file.toURI();URL url=uri.toURL();clip=Applet.newAudioClip(url);}catch(Exception ee){} }
}

Record类

package ch8.view;
import javax.swing.*;
import java.awt.event.*;
import ch8.data.RecordOrShowRecord;
public class Record extends JDialog implements ActionListener{int time=0;String grade=null;String key=null;String message=null;JTextField textName; JLabel label=null; JButton confirm,cancel;public Record(){setTitle("记录你的成绩");this.time=time; this.grade=grade;setBounds(100,100,240,160);setResizable(false);setModal(true); confirm=new JButton("确定");cancel=new JButton("取消");textName=new JTextField(8);textName.setText("匿名");confirm.addActionListener(this);cancel.addActionListener(this);setLayout(new java.awt.GridLayout(2,1));label=new JLabel("输入您的大名看是否可上榜");add(label);JPanel p=new JPanel();p.add(textName);p.add(confirm);p.add(cancel);add(p);setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE);}public void setGrade(String grade){this.grade=grade;}public void setTime(int time){this.time=time;}public void actionPerformed(ActionEvent e){if(e.getSource()==confirm){String name = textName.getText();writeRecord(name,time);setVisible(false);}if(e.getSource()==cancel){setVisible(false);}  }public void  writeRecord(String name,int time){RecordOrShowRecord rd = new RecordOrShowRecord();rd.setTable(grade);boolean boo= rd.addRecord(name,time);if(boo){JOptionPane.showMessageDialog(null,"恭喜您，上榜了","消息框", JOptionPane.WARNING_MESSAGE); }else {JOptionPane.showMessageDialog(null,"成绩不能上榜","消息框", JOptionPane.WARNING_MESSAGE); } }
}

ShowRecord类

package ch8.view;
import java.awt.*;
import javax.swing.*;
import ch8.data.RecordOrShowRecord;
public class ShowRecord extends JDialog {String [][] record;JTextArea showMess;RecordOrShowRecord rd;//负责查询数据库的对象public ShowRecord() {rd = new RecordOrShowRecord();showMess = new JTextArea();showMess.setFont(new Font("楷体",Font.BOLD,15));add(new JScrollPane(showMess));setTitle("显示英雄榜");setBounds(400,200,400,300);setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);}public void setGrade(String grade){rd.setTable(grade);}public void setRecord(String [][]record){this.record=record;}public void showRecord() {showMess.setText(null);record = rd.queryRecord();if(record == null ) {JOptionPane.showMessageDialog(null,"没人上榜呢","消息框", JOptionPane.WARNING_MESSAGE);}  else {for(int i =0 ;i<record.length;i++){int m = i+1;showMess.append("\n英雄"+m+":"+record[i][0]+"         "+"成绩:"+record[i][1]);showMess.append("\n--------------------------------");}setVisible(true);}}
} 

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[][] = new 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。
