package step3;

import java.io.; import java.net.; // TCP客户端 public class TCPClient { public static void main(String[] args) throws Exception { MyTCPServer myTCPServer = new MyTCPServer(); myTCPServer.start(); // ---------------------Begin------------------------ // 创建一个Socket并连接到指定的服务器端,完成与服务端交流 DatagramSocket socket = new DatagramSocket(); String message = 'Hello udp'; byte[] data = message.getBytes(); InetAddress address = InetAddress.getLocalHost(); int port = 8900; DatagramPacket packet = new DatagramPacket(data, data.length, address, port); socket.send(packet); // ---------------------End------------------------
