Java Socket模拟客户端和服务端通信

服务端

import java.io.*;
import java.net.ServerSocket;
import java.net.Socket;

public class Server {
    public static void main(String[] args) throws IOException {
        int port = 8888;
        //开启一个服务端ServerSocket
        try (ServerSocket serverSocket = new ServerSocket(port)) {

            //监听socket连接
            Socket socket = serverSocket.accept();
            //获取socket连接的输入流
            InputStream inputStream = socket.getInputStream();

            //用数据传输流包装输入流
            DataInputStream dataInputStream = new DataInputStream(inputStream);

            String s = dataInputStream.readUTF();
            System.out.println("客户端传输过来的数据是： " + s);

            //获取socket连接的输出流
            OutputStream outputStream = socket.getOutputStream();
            DataOutputStream dataOutputStream = new DataOutputStream(outputStream);
            dataOutputStream.writeUTF("服务端已经收到你的数据,over"
