Question

我对我希望客户按顺序与服务器通信的方式感到困惑。例如，我正在创建一个多人tic tac toe游戏，其中2个客户端将连接到游戏服务器。然后客户轮流放入x的坐标。但是，当我在while循环中使用break时，它只允许它们在断开套接字之前输入一次。我如何做到这样，客户端被暂时阻止而另一个客户端回答？

编辑：我不打算为此目的使用多线程。

服务器（为了阅读而截断）：

try {
        while (true) {
            System.out.println("Awaiting connection!");
            Socket clientSocket = server.accept();
            System.out.println("Player " + noOfPlayers + " has connected!");
            noOfPlayers ++;
            out = new PrintWriter(clientSocket.getOutputStream(), true);
            in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));

            while (!newGame.checkWinner()) {
                out.println(newGame.currentPlayer());
                input = in.readLine();
                x = Integer.parseInt(input.split("\\,+")[0]);
                y = Integer.parseInt(input.split("\\,+")[1]);
                newGame.addPoint(x, y);
                out.println("Moved");
                if (newGame.checkWinner()) {
                    System.out.println("The winner is " + newGame.currentPlayer());
                    out.println("The winner is " + newGame.currentPlayer());
                    server.close();
                    break;
                }
                else if (newGame.boardFilledUp()) {
                    newGame.loadBoard();
                    out.println("It's a draw!");
                    server.close();
                    break;
                }
                newGame.loadBoard();
                newGame.changePlayer();
                break;
            }
        }
    } catch (Exception e) {
        System.out.println(e.getMessage());
    }

客户端（因阅读而被截断）：

while (true) {
        PrintWriter out = new PrintWriter(echoSocket.getOutputStream(), true);
        // Read input from server
        BufferedReader in = new BufferedReader(new InputStreamReader(echoSocket.getInputStream()));
        // Read input from client
        BufferedReader stdIn = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Enter your coordinates in x,y form: ");
        String userInput;
        char serverOutput;
        serverOutput = in.readLine().charAt(0);
        System.out.println("Current player is " + serverOutput);
        while ((userInput = stdIn.readLine()) != null) {
            out.println(userInput);
            System.out.println("You sent: " + userInput);
        }
        break;
    }

Answer 1

找出问题所在。我没有刷新PrintWriter。

允许客户端按顺序与服务器通信
