Independent on UDP or TCP the simplest way with Socket is

public int ping(String server, int port) {
      try {
            Socket s = new Socket(server, port);
            s.setSoLinger(true, 0);
            s.close();
            return 1; // available
      } catch (Exception e) { }
      return 0; // not available
}
