@karianna : This will blow out the back of the stack - are you sure you want to do this?

@karianna: Can we use Timer and TimerTask instead of using Thread.sleep() to pause and repeat task?

[karianna]

You're better off using Threadpools and countdown latches. Timer and TimerTask are older concurrency constructs. Ping Ben for a quick tutorial/explanation

Okay thanks for the tips, is it worth looking at the adv java notes - i do recall these topics being covered!

[karianna]

I don't think we covered Semaphores in the course.... Nope, not explicitly. Have you got a copy of Java Concurrency in Practice? I'm afraid that my knowledge in this space is more theoretical than based on 10,000 hours of practice, so I'd recommend channeling Brian or chatting to Ben
