package bb;

	{
		try{
		bbaa.t.wait();

}

why the wait is not working?

[Roger Sterling]

We need two things : 1. put your code in [c ode] tags and 2. Please ask a specific question in the context of what you tried to do to fix your issue.

[Chan Ag]

Roger is right. Please UseCodeTags while posting code ( of any length ).
I've added them.to your post this time.

Also please note that ItDoesntWorkIsUseless
So please ask specific questions, as that increases your chances
of getting a help here.

Your wait needs to be in a synchronized block of some form ;-) or you'll get a nasty run time error ;-)

After that you'll need a notify in another thread if you want your wait to wake up (or a time limit on the wait itself).
