1. 客户端代码：Client.java

package com.xie.javase.net1;

import java.io.*;
import java.net.*;

public class Client {
   
    public static void main(String[] args) {
   
        Socket socket = null;
        BufferedWriter bw = null;
        
        try {
   
            // 1. 获取本机IP地址对象
            InetAddress localHost = InetAddress.getLocalHost();
            int port = 8888;

            // 2. 创建Socket并连接服务端
            socket = new Socket(localHost, port);
            
            // 3. 获取输出流并包装为缓冲字符流
            bw = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
            
            // 4. 发送数据（注意每条消息末尾添加换行）
            bw.write("落霞与孤鹜齐飞");
            bw.newLine();  // 更规范的换行写法（自动适配系统）
            bw.write("秋水共长天一色"
