一、需求分析《2048》是比较流行的一款数字游戏。

原版2048首先在github上发布，原作者是Gabriele Cirulli。

它是基于《1024》和《小3传奇》的玩法开发而成的新型数字游戏[1]。

随后2048便出现各种版本，走各大平台。

由Ketchapp公司移植到IOS的版本最为火热，现在约有1000万下载，其名字跟原版一模一样。

衍生版中最出名的是《2048六边形》版本，先后在全球81个国家中的board game中排进了前200。

安卓版非常火爆的有《挑战2048》，其2.0.0版以后还加入了双人对战。

其次比较特别的有2048中国朝代版。

更有2048自定义版，可以自己定义文字和图片。

《2048》是IOS中流行的一款。

本课程设计通过设计与开发JVM平台上的2048游戏，进一步掌握所学Java课程的知识，体验Java的跨平台性，同时将Java设计方面的知识拓展应用二、系统运行环境1、硬件环境：2、软件环境：操作系统：WindowsXP/Windows7软件：集成开发环境Eclipse三、功能需求描述1、图形用户界面：2048的最大特点就是玩家对图形界面里的数字进行操作，也就是是玩家与游戏的互动2、当前分数SCORE与最高分数的显示：在我们设计的2048游戏中当前分数取了页面内所有数字相加的值为分数，对玩家玩游戏的进展有直接性、客观性的展现；同时，最高分数取了以往玩家退出游戏时所保存分数的最高分3、数字颜色：游戏中数字的颜色以2为首项的等比数列变化，即2、4、8、16、32、64、128、256、512、1024、2048.......对应的数字卡片变色4、游戏的退出：游戏退出时，我们采用弹出对话框的确认玩家是否真的要退出游戏，当然这样做更符合游戏人性化设计的观念。

功能图如下：四、总体设计简要设计流程：程序结构说明：//重新开始，若是初次运行游戏，则从文件中读入最高分void restart()//控制方法public void keyPressed(KeyEvent e)//绘图方法public void paint(Graphics g)//判断是否已经失败，若失败则返回true，否则返回falsepublic boolean judgeFail()//向下滑动，若各列均没有方块相消或移动，则返回false，否则返回true；public void moveDown()//向左滑动，若各行均没有方块相消或移动，则返回false，否则返回true；public void moveLeft()//向右滑动，若各行均没有方块相消或移动，则返回false，否则返回true；public void moveRight()//向上滑动，若各行均没有方块相消或移动，则返回false，否则返回true；Public void moveUp()//在游戏区空闲处随机生成2或4public void generateRandom2or4()五、程序模块设计源码如下：Main类：import javax.swing.JFrame;public class Main {public static void main(String[] args){JFrame frame=new Java2048();frame.setTitle("Java2048");frame.setSize(455,610);frame.setLocationRelativeTo(null);frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE );frame.setVisible(true);}}Java2048类：import java.awt.*;import java.awt.event.*;import java.io.*;import java.util.*;import javax.swing.*;public class Java2048 extends JFrame implements KeyListener{ private static final long serialVersionUID = 1L;Color background = new Color(190, 173, 160);// 背景色Color foreground = new Color(204, 192, 178);// 前景色Color wordColor = new Color(232, 216, 203);// 单词色Font wordFont = new Font("微软雅黑", Font.PLAIN, 20);// 单词字体Font numberFont = new Font("微软雅黑", Font.BOLD, 40);// 数字字体Random random=new Random();//随机数发生器int[][] array;//游戏用2维数组//逐行或逐列处理数组，第一个参数为实际数字，第二个为判断值，用来判断是否应该消除相同的数字int[][] process=new int [4][2];int score;//分数，初始化为零int highestScore;//游戏中最高分int highestScore2=0;//文件中最高分int biggestNumber=0;boolean ifGenerate2or4;int[] rd=new int[16];//生成随机2或4的位置private Graphics gBuffer;//构造方法public Java2048(){addKeyListener(this);addWindowListener(new WindowAdapter(){public void windowClosing(WindowEvent e){if(JOptionPane.showConfirmDialog(null, "确定退出？", "提示", JOptionPane.YES_NO_OPTION)==JOptionPane.YES_NO_OPTION){if(highestScore>highestScore2){//若在本次游戏中破了纪录，则更新文件中的最高分highestScore2=highestScore;File file=new File("Java2048beta1.txt");BufferedWriter bw;try{bw=new BufferedWriter(new FileWriter(file));bw.write(String.valueOf(highestScore2),0,String.valueOf(highestScore2).length());bw.close();}catch(Exception e1){ JOptionPane.showMessageDialog(null,"找不到同目录下Java2048beta1.txt文件或文件已损坏!", "提示", RMATION_MESSAGE);};}System.exit(0);}}});restart();}void restart(){//重新开始//若是初次运行游戏，则从文件中读入最高分if(highestScore==0){}File file=new File("Java2048beta1.txt");BufferedReader br;try{br=new BufferedReader(new FileReader(file));highestScore2=Integer.valueOf(br.readLine());br.close();}catch(Exception e){JOptionPane.showMessageDialog(this,"找不到同目录下Java2048beta1.txt文件或文件已损坏!", "提示", RMATION_MESSAGE);System.exit(0);};highestScore=highestScore2;array=new int[4][4];//清空游戏用2维数组score=0;//重置分数为零biggestNumber=0;//重置最大数字为零//在游戏区随机生成两个2或4generateRandom2or4();generateRandom2or4();}//绘图方法public void paint(Graphics g) {gBuffer=g;gBuffer.setColor(background);gBuffer.drawRoundRect(30, 40, 185, 90, 20, 20);// 画分数显示区gBuffer.fillRoundRect(30, 40, 185, 90, 20, 20);gBuffer.drawRoundRect(245, 40, 185, 90, 20, 20);// 画最高分显示区gBuffer.fillRoundRect(245, 40, 185, 90, 20, 20);gBuffer.drawRoundRect(0, 150, 454, 460, 10, 10);// 画主游戏区gBuffer.fillRoundRect(0, 150, 454, 460, 10, 10);gBuffer.setFont(wordFont);gBuffer.setColor(wordColor);gBuffer.drawString("SCORE", 90, 70);// 画SCOREgBuffer.drawString("BEST", 315, 70);
