基于java的组播组中发送和接受数据实例.zip

import java.net.*; import java.io.*; public class MulticastServer{ String groupHost="232.0.0.1"; //组播组虚拟IP int port=5678; //端口 public MulticastServer(){ try{ MulticastSocket multicastSocket = new MulticastSocket(port); //MulticastSocket实例 InetAddress inetAddress = InetAddress.getByName(groupHost); //组地址 multicastSocket.joinGroup(inetAddress); //加入到组播组中 while (true){ byte[] received = new byte[128]; //接收数据缓冲 DatagramPacket datagramPacket = new DatagramPacket(received, received.length); //接收数据的数据报 multicastSocket.receive(datagramPacket); //接收数据 System.out.println(new String(received)); //输出接收到的数据 } } catch (Exception exception){ exception.printStackTrace(); //输出出错信息 } } public static void main(String [] arstring){ new MulticastServer(); } }
