实现了TCP的单向通信

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"
