You can execute below snippet to get this..

public class UdpServer {

        public static void main(String[] args) {
        int port = 2350;

        try{
                //SocketAddress sa = new InetSocketAddress(port);
                //DatagramSocket ds = new DatagramSocket(sa);
                DatagramSocket ds = new DatagramSocket();

                //ds.setTrafficClass(1);
                System.out.println("get traffic class " + ds.getTrafficClass());
        }catch(Exception exp) {
                exp.printStackTrace();
        }

        }
