一个MulticastSocket可以多次调用joinGroup()方法,加入到多个组播组。此外,同一个主机上的多个MulticastSocket,或者主机的同一程序内的多个MulticastSocket可以加入到同一个组播组,每个MulticastSocket都会接收到发往该组的数据。joinGroup()方法有两种重载形式: publicvoidjoinGroup(InetAddressaddress)throwsIOExceptionpublicvoi...
创建MulticastSocket对象后,还需要将该MulticastSocket加入到指定的多点广播地址,MulticastSocket使用joinGroup()方法加入指定组;使用leaveGroup()方法脱离一个组。 1、joinGroup(InetAddress multicastAddr):将该MulticastSocket加入指定的多点广播地址。 2、leaveGroup(InetAddress multicastAddr):让该MulticastSocket离开指定的...

首先使用所需端口创建MulticastSocket,然后调用joinGroup(InetAddress groupAddr)方法,即可加入组播组: // join a Multicast group and send the group salutations ... String msg = "Hello"; InetAddress group = InetAddress.getByName("228.5.6.7"); MulticastSocket s = new MulticastSocket(6789); s.joinGro...
可以通过首先使用所需端口创建 MulticastSocket,然后调用joinGroup(InetAddress groupAddr)方法来加入多播组: // join a Multicast group and send the group salutations ... String msg = "Hello"; InetAddress group = InetAddress.getByName("228.5.6.7"); MulticastSocket s = new MulticastSocket(6789); s....
multicastSocket.joinGroup(address); (2)发送方法 multicastSocket.send(datagramPacket); (3)接受方法 multicastSocket.receive(datagramPacket); // 接收数据,同样会进入阻塞状态 这里贴上客户端code: import java.io.IOException; import java.io.InputStream; ...
