我在Java中遇到了这个服务器客户端程序。我的程序到了

System.out.println("Check1");
String name = in.nextLine();
BoardServer

然后它就在那里,没有任何东西被发送到客户端。

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.PrintWriter;
import java.util.Scanner;


public class BoardServer {
    private static Scanner in;
    private static PrintWriter out;
    private static int num = 1;

    public static void main(String[] args) throws IOException {

        final int SBAP_PORT = 8888;
        ServerSocket server = new ServerSocket(SBAP_PORT);
        System.out.println("Waiting for players to connect...");

        while (true) {
            Socket s = server.accept();
            in = new Scanner(s.getInputStream());
            out = new PrintWriter(s.getOutputStream());
            System.out.println("Check1");
            String name = in.nextLine();
            System.out.println("Check2");
            String message = "Hello " + name + " you are player number " + num;
            num++;
            System.out.println("Check3");
            out.print(message);
            out.flush();
            System.out.println("player connected.");
            Player client = new Player(s);
            Thread t = new Thread(client);
            t.start();
        }
    }
}

使用以下命令将名称发送到服务器时

out.print(name);

使用

out.println(name);

如果要在服务器上使用in.nextLine()读取它,请发送它。这应该可以解决你的问题。
