Sending Information Over the Internet - - meh...?

is there any simple way of telling JVM to listen to port X, and is there a way of telling JVM to send a UDP packet to "thisIP" through "thisPort" with "thisData"?

maybe some built in object that has a constructor like:

udpPacket(String thisIP, int thisPort, String thisData){}

and then a "send()" method?

if not could someone throw up some sorta common IP or TCP class or whatever would b neccesary to simply send and recieve text over the innerwebz? :P
