JAVA面向对象编程程序设计——中国象棋

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。

5.客户端，服务端发送的信息类。

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;
    }

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 void socket() throws IOException {
        try {
            ServerSocket ss = new ServerSocket(1065);
            System.out.println("启动服务器....");
            Socket s = ss.accept();
            while(true) {
                System.out.println("客户端:" + s.getInetAddress().getLocalHost() + "已连接到服务器");
                BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));
                //读取客户端发送来的消息
                String mess = br.readLine();
                System.out.println("客户端：" + mess);
                BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
                bw.write(mess + "\n");
                bw.flush();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    public static void main(String[] args) throws IOException {
        new Server().socket();
    }
}

六、运行截图

单机版的运行

网络对战版(未完成)

七、尚待改进

1.象棋的网络对站因为javaFX的传参问题而未能实现，考虑改为swing重新设计；
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。
