Returns the binding state of the socket.

Usage

From source file:Main.java

public static void main(String args[]) {
    try {/*from  w w w . j a  va 2 s. c o  m*/

        InetAddress ia = InetAddress.getByName("www.java2s.com");

        DatagramSocket ds = new DatagramSocket();

        byte buffer[] = "hello".getBytes();
        DatagramPacket dp = new DatagramPacket(buffer, buffer.length, ia, 80);

        // Send the datagram packet
        ds.send(dp);

        System.out.println(ds.isBound());
    } catch (Exception e) {
        e.printStackTrace();
