Question

我一直在创建一个小游戏，涉及用户在生成的客户端输入数字但服务器。我让它在一个循环中工作，但我无法保持游戏的进行。

一旦用户输入他们的号码，服务器将在需要的地方给出分数，我尝试在下面的行周围添加一个for循环，但这只是打印使用用户的第一个输入。

如何更改代码，以便服务器为客户端发出新号码，而不只是使用用户的第一个号码？

试图循环播放此代码

                int n = light();
                String binString = lightBin(n);
                String check = Integer.toString(n);
                System.out.println(binString);

                outToClient.println("Turning on light " + n);

                fromclient = inFromClient.readLine();
                System.out.println("User pressed light " + fromclient);

                score = scoreCheck(check, fromclient);
                System.out.println("Score = " + score);

您的客户端代码应该是

 while (true) { // but you must specify some condition to stop the while
            FromServer = inFromServer.readLine();
            System.out.println(FromServer);

            PrintWriter outToServer = new PrintWriter(client.getOutputStream(), true);
            ToServer = inFromUser.readLine();

            outToServer.println(ToServer);
            outToServer.flush();
        }

和您的服务器端代码

while (true) { // but you must specify some condition to stop the while
                outToClient.println("Turning on light " + n);
                outToClient.flush();
                fromclient = inFromClient.readLine();
                System.out.println("User pressed light " + fromclient);

                score = scoreCheck(check, fromclient);
                System.out.println("Score = " + score);
            }
