when you have a thread and you want to stop it you can call on this thread the method interrupt(), but this interrupt method will only set a variable of type boolean to true, every call to this.isInterrupted() will return the value of this variable. The only problem is: your thread goes to the not running state, any call to interrupt() will, specially in this case, restart the thread and then throw new InterruptedException(), conclusion: InterruptedException must be catch whenever you intend to make the thread sleep, or wait, if the thread is interrupted in the running state no exceptions are thrown, if it is sleeping, it's dreams will be interrupted and then a new InterruptedException will be created!!!
Please, correct me if I'm wrong. Hope this helps!
