Thank you.

Note the use of extends in the class definition. public class myUDP extends UDP{ String myIp; int myPort; String inMsg; boolean inMsgrdy; public myUDP( String ip, int port) { super(port); //super(this, ip, port) this not allowed this should be the UDP constructor super.setReceiveHandler("receivea"); //this does nothing myIp = ip; myPort = port; super.log…
