JAVA面向对象编程程序设计—

一、团队介绍

连正(队长) | 棋盘的实现，棋子的行动，界面的设计等
王浩天 | 棋局规则(各子的行动限制)，网络对战

二、项目gitee地址

https://gitee.com/immutablelupo/china-chess

三、项目流程图

四、面向对象设计图

1.实现两方兵的行走规则。

2.初始化棋盘，其他棋子的行走规则，棋子的选取等。

3.棋子的坐标。棋子的初始落位。

4.两个客户端之间的信息处理。

五、项目关键代码

兵的移动：一次只能移动一格，判断并是否在敌方半场来确定可移动的方向

public static List<Integer[]> bingMove(Chess chess ){int i = chess.getI();int j = chess.getJ();if(chesses[j][i] != chess){System.out.println("exp");}List<Integer[]> list = new ArrayList<>();if(Main.colorR.equals(chess.getColor())){if(j<5){if(j>0){if(chesses[j-1][i] ==null){Integer[] integers = {i,j-1};list.add(integers);}else{if(!chesses[j-1][i].getColor().equals(chess.getColor())){Integer[] integers = {i,j-1};list.add(integers);}}}if(i>0){if(chesses[j][i-1] ==null){Integer[] integers = {i-1,j};list.add(integers);}else{if(!chesses[j][i-1].getColor().equals(chess.getColor())){Integer[] integers = {i-1,j};list.add(integers);}}}if(i<9){if(chesses[j][i+1] ==null){Integer[] integers = {i+1,j};list.add(integers);}else{if(!chesses[j][i+1].getColor().equals(chess.getColor())){Integer[] integers = {i+1,j};list.add(integers);}}}}}return list;}

整个棋盘的实现

棋子移动时触发的“吃”，和胜利的判定

 public void PlayChess(int i,int j, GraphicsContext gc){Chess chess = CanvasUtils.clickChess(i*girdW,j*girdH);if(chess != null){if(selectChess == null ){if(chess.getColor().equals("R")&&roundchange==0||chess.getColor().equals("B")&&roundchange==1){{if(roundchange==0){roundchange = roundchange + 1;}else if(roundchange==1){roundchange = roundchange - 1;}System.out.println(roundchange);CanvasUtils.selectChess(chess, gc);}}}else{CanvasUtils.moveChess(i, j, gc);//吃棋子if(Tool!=null) {if (Tool.chessName.equals("帥") || Tool.chessName.equals("將"))System.out.println("win!");}}}else{CanvasUtils.moveChess(i, j, gc);//移动到没有棋子的地方if(Tool!=null) {if (Tool.chessName.equals("帥") || Tool.chessName.equals("將"))System.out.println("win!");}}}

服务器，读取并转发客户端送来的信息。

public class Server {ServerSocket serverSocket = null;static Map<Integer, Socket> map = new HashMap<Integer, Socket>();public static int i=1;public static int flag3=0;public static BufferedWriter bwa = null;public static BufferedWriter bwb = null;public void socket() throws IOException {try {ServerSocket ss = new ServerSocket(8887);System.out.println("启动服务器....");//客户端1ExecutorService executor= Executors.newFixedThreadPool(1);CompletableFuture<String> future2 = CompletableFuture.supplyAsync(()-> {try {System.out.println("异步启动:");try {while(true) {Socket s1 = ss.accept();InetAddress inetAddress=s1.getInetAddress();System.out.println("客户端:" +"2:"+ s1.getInetAddress().getLocalHost() + "已连接到服务器");flag3++;i++;System.out.println(i);if (s1 != null) {try {while(true) {// 3.获取socket通道的输入流(输入流的读取方式为一行一行的读取方式 ----> readLine())// 4.获取通道的输入流(也是一行一行的写出  BufferedWriter ->newLine())// 当用户点击“发送”按钮的时候才会，写出数据BufferedReader br1 = new BufferedReader(new InputStreamReader(s1.getInputStream()));Server.bwb = new BufferedWriter(new OutputStreamWriter(s1.getOutputStream()));if(flag3==2){String line1="双方棋手已就位,请红色方先开始棋局";bwa.write(line1);System.out.println("服务端发送信息:"+line1);bwa.newLine(); // 换行bwa.flush();  //bwb.write(line1);System.out.println("服务端发送信息:"+line1);bwb.newLine(); // 换行bwb.flush();  //}String line = null;while ((line = br1.readLine()) != null) {System.out.println("客户端发送信息:" + line);// 将读取的数据拼接到文本域中显示if (line.contains("#")) {bwa.write(line);System.out.println("服务端发送信息:"+line);bwa.newLine(); // 换行bwa.flush();  //}}System.out.println(line);}} catch(Exception e){e.printStackTrace();}}}} catch (IOException e) {e.printStackTrace();}Thread.sleep(5000);return "finish";} catch (InterruptedException e) {System.err.println("错误！");return "wrong！";}},executor);//客户端2while (true) {Socket s2 = ss.accept();InetAddress inetAddress = s2.getInetAddress();System.out.println("客户端:" + "1:" + s2.getInetAddress().getLocalHost() + "已连接到服务器");flag3++;if (s2 != null) {try {while (true){// 3.获取socket通道的输入流(输入流的读取方式为一行一行的读取方式 ----> readLine())// 4.获取通道的输入流(也是一行一行的写出  BufferedWriter ->newLine())// 当用户点击“发送”按钮的时候才会，写出数据BufferedReader br1 = new BufferedReader(new InputStreamReader(s2.getInputStream()));Server.bwa = new BufferedWriter(new OutputStreamWriter(s2.getOutputStream()));if(flag3==2){String line1="双方棋手已就位,请红色方开始棋局";bwa.write(line1);System.out.println("服务端发送信息:"+line1);bwa.newLine(); // 换行bwa.flush();  //bwb.write(line1);System.out.println("服务端发送信息:"+line1);bwb.newLine(); // 换行bwb.flush();  //}String line = null;while ((line = br1.readLine()) != null) {System.out.println("客户端发送信息:" + line);// 将读取的数据拼接到文本域中显示bwb.write(line);System.out.println("服务端发送信息:"+line);bwb.newLine(); // 换行bwb.flush();  //}System.out.println(line);}} catch (Exception e) {e.printStackTrace();}}}} catch (IOException e) {e.printStackTrace();}}public static void main(String[] args) throws IOException {new Server().socket();}
}

七、客户端发送信息

public void sendServer(String msg){try {bw1.write(msg);bw1.newLine(); // 换行bw1.flush();  //} catch (IOException e) {e.printStackTrace();}}

八、客户端接收信息

btn.setOnAction(actionEvent -> {ExecutorService executor= Executors.newFixedThreadPool(1);CompletableFuture<String> future2 = CompletableFuture.supplyAsync(()-> {try {try{/*******客户端 TCP协议*********/// 1.创建一个客户端的套接字（尝试连接）Socket socket = new Socket("127.0.0.1",8887);// 2.获取socket通道的输入流BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));bw1 = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));String line = null;while((line = br.readLine()) !=null){textarea.appendText("服务器发送信息:"+line);if(line.contains("#")){String ti=String.valueOf(line.charAt(1));String tj=String.valueOf(line.charAt(2));String ta=String.valueOf(line.charAt(3));String tb=String.valueOf(line.charAt(4));System.out.println(ti+tj+ta+tb);updateChess(Integer.parseInt(ta),Integer.parseInt(tb),Integer.parseInt(ti),Integer.parseInt(tj),gc);textarea.appendText("对方落子:"+line.substring(1,3)+"-->"+line.substring(3,5));stop=0;if(roundchange==1){roundchange = roundchange - 1;}else if(roundchange==0){roundchange=roundchange+1;}}if(line.contains("@")){textarea.appendText(line);}}System.out.println(line);// 3. 获取输出流// 4.关闭流socket.close();/******************************/}catch(Exception e){e.printStackTrace();}Thread.sleep(5000);return "finish";} catch (InterruptedException e) {System.err.println("错误！");return "wrong！";}},executor);});

六、运行截图

单机版的运行

网络对战版

两者连接

七、尚待改进

1.象棋走棋提示不是很完善，登陆系统也没有实现；
2.课设虽然很早已经开始让我们考虑，由于其他学科和考试等原因在计网课设之后才开始，时间太短界面过于简陋。
