Constructs a datagram socket and binds it to any available port on the local host machine.

Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    byte[] inbuf = new byte[256]; // default size
    DatagramSocket socket = new DatagramSocket();

    DatagramPacket packet = new DatagramPacket(inbuf, inbuf.length);
    socket.receive(packet);//from ww  w . j a  v a  2 s  .com

    int numBytesReceived = packet.getLength();
    System.out.println(numBytesReceived);
}

From source file:Main.java

public static void main(String[] argv) throws Exception {

    byte[] outbuf = new byte[1024];
    int port = 1234;
    DatagramSocket socket = new DatagramSocket();
    InetAddress groupAddr = InetAddress.getByName("8.1.2.3");
    DatagramPacket packet = new DatagramPacket(outbuf, outbuf.length, groupAddr, port);
    socket.send(packet);/*from  w  w  w .ja va  2  s  . com*/
