Serach at google for Ping.java. In other words, you must implement a simple ping to a predefined host.

Not sure if there's a definitive way to check.
pinging as ovi suggested is probably the best solution, although if the machine you ping is down, or the net is slow (causing timeout) then the ping will fail making it appear that you are not connected when in fact you are.
