在Java中,可以使用java.net.MulticastSocket类来实现UDP组播的编程。MulticastSocket类是DatagramSocket类的子类,它支持发送和接收UDP组播数据包。 下面是一个简单的Java UDP组播的示例代码: importjava.net.*;publicclassMulticastExample{publicstaticvoidmain(String[]args)throwsException{InetAddressgroup=InetAddress.getByN...
The multicast datagram socket class is useful for sending and receiving IP multicast packets.C# 複製 [Android.Runtime.Register("java/net/MulticastSocket", DoNotGenerateAcw=true)] public class MulticastSocket : Java.Net.DatagramSocketInheritance Object Object DatagramSocket MulticastSocket ...
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...
使用MulticastSocket实现多点广播: (1)DatagramSocket只允许数据报发给指定的目标地址,而MulticastSocket可以将数据报以广播的方式发送到多个客户端。 (2)IP协议为多点广播提供了这批特殊的IP地址,这些IP地址的范围是:224.0.0.0至239.255.255.255.. (3)MulticastSocket类时实现多点广播的关键,当MulticastSocket把一个Daragr...
1.创建MulticastSocket对象:首先,通过创建一个MulticastSocket对象来建立与组播IP地址和端口的连接。例如,可以使用以下代码创建一个MulticastSocket对象: ``` MulticastSocket multicastSocket = new MulticastSocket(8888); ``` 2.绑定组播IP地址和端口:接下来,使用`joinGroup(InetAddress group)`方法将MulticastSocket绑定...
