Socket编程如何实现服务器端接收客户端数据

1.服务器端代码:

public class Service {

    public static void main(String[] args) {

        try {
            ServerSocket server = new ServerSocket(8888);
            Socket socket = server.accept();
            InputStream in = socket.getInputStream();
            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(in));
            System.out.println(reader.readLine());
            socket.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

2.客户端:

public class User {
    public static void main(String[] args) {
        while (true) {
            try {
                Socket socket = new Socket("127.0.0.1", 8888);
                BufferedReader reader = new BufferedReader(
                        new InputStreamReader(System.in));
                String s = reader.readLine();
                PrintWriter writer = new PrintWriter(new BufferedWriter(
                        new OutputStreamWriter(socket.getOutputStream())), true);
                writer.println(s);
                socket.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
}
