User

Server

package com.imooc.UTPReturn;import java.io.ByteArrayInputStream;import java.io.ObjectInputStream;import java.net.DatagramPacket;import java.net.DatagramSocket;import java.net.InetAddress;public class UTPServer {public static void main(String[] args) throws Exception {/* * 服务器端接收客户端的请求 */// 创建服务器端DatagramSocketDatagramSocket socket = new DatagramSocket(8800);// 创建数据包byte[] data = new byte[1024];DatagramPacket packet = new DatagramPacket(data, data.length);// 服务器端已经启动...System.out.println("服务器端已经 启动....");socket.receive(packet);// 接收数据// 读取客户端发来的数据// String str=new String(data, 0, packet.getLength());// System.out.println("我是服务器，客户端说："+str);// bytearray to objectByteArrayInputStream bi = new ByteArrayInputStream(data);ObjectInputStream oi = new ObjectInputStream(bi);User user = (User)oi.readObject();bi.close();oi.close();System.out.println(user.toString());/* * 服务器端回应客户端 */// 给客户端发出响应byte[] responseData = null;responseData = "欢迎你".getBytes();InetAddress address = packet.getAddress();int port = packet.getPort();DatagramPacket responsePacket = new DatagramPacket(responseData,responseData.length, address, port);socket.send(responsePacket);// 关闭资源socket.close();}}

Client
