newbie question on threads

[Gonçalo Rodrigues]

Hi,

I just started out studying threads and fleshing out my first
multithreaded app. But there is still one thing that I'm not completely
sure: If a thread acesses a shared object via a non-altering state
method, and without locking, is this safe? Or even in this case we might
run into problems? Better safe-than-sorry strategy?

Thanks in advance,
