THREADING IN JAVA

------------------------------------------------------------------------------------------------------------------------------------------------

------------------------------------------------------------------------------------------------------------------------------------------------

Q Create two Thread subclasses, one with a run( ) that starts up and then calls wait( ). The other class’ run( ) should capture the reference of the first Thread object. Its run( ) should call notifyAll( ) for the first thread after some number of seconds have passed, so the first thread can print a message.
