Getting a thread to throw an exception

[jjamesis]

Sorry if this is in the wrong place, can a mod move it if it is?

Is it possible to get the run method inside a thread to throw an exception?
If I describe the problem maybe I can get some advice on a different way to go about this.

I have a main class class1 which creates a thread (class2) and executes some code within a timelimit. If class1 takes too long the thread should throw back an exception.

try
{
Class2 myThread = new Class2();
myThread.start();

// do some stuff here within timelimit

}
catch (Exception e)
{
e.printStackTrace();
}

The best I can do it to get the thread to print "time out" when the timelimit
is over and class1 is still executing.

The problem is, the run method of a thread cannot throw exceptions.
Is there a way around this? Is there a better to go about what I'm doing?

Thanks
