MulticastSocket MulticastSocket(SocketAddress) in Java

MulticastSocket(SocketAddress): This method is available in the java.net.MulticastSocket class of Java.

Syntax:

java.net.MulticastSocket.MulticastSocket(SocketAddress bindaddr) throws IOException

This method takes one argument. This method creates a multicast socket, bound to the specified local socket address.

If the address is null an unbound socket will be created.

Parameters: One parameter is required for this method.

bindaddr: Socket address to bind to, or null for an unbound socket.

Throws:

1. IOException - if an I/O exception occurs while creating the MulticastSocket.

2. SecurityException - if a security manager exists and its checkListen method doesn't allow the operation.

Approach

Java

package com.MulticastSocket;

import java.io.IOException;
import java.net.InetSocketAddress;
import java.net.MulticastSocket;
import java.net.SocketAddress;

public class MulticastSocket3 {
    public static void main(String[] args) throws IOException {

        int port = 8080;
        SocketAddress bindaddr = new InetSocketAddress(port);
        MulticastSocket multicastSocket = new MulticastSocket(bindaddr);

        System.out.println(multicastSocket);
    }
}

Output:

java.net.MulticastSocket@63d4e2ba

MulticastSocket(): This method constructs a multicast socket and binds it to any available port on the local host machine. 

MulticastSocket(int): This method constructs a multicast socket and binds it to the specified port on the local host machine.

MulticastSocket(SocketAddress): This method creates a multicast socket, bound to the specified local socket address.

getNetworkInterface(): This method gets the multicast network interface set.

getTimeToLive(): This method gets the default time-to-live for multicast packets sent out on the socket.

joinGroup(SocketAddress, NetworkInterface): This method joins the specified multicast group at the specified interface.

leaveGroup(SocketAddress, NetworkInterface): This method leaves a multicast group on a specified local interface.

setNetworkInterface(NetworkInterface): This method specifies the network interface for outgoing multicast datagrams sent on this socket.

setTimeToLive(int): This method sets the default time-to-live for multicast packets sent out to this MulticastSocket in order to control the scope of the multicast.
