Couple Questions on Thread

[Lil_Aziz1]

I'm not getting join() method.
t.join() waits for the thread t to die.
So it's waiting for itself to die? Why?
What does it mean for a thread to "die?"
What happens after it dies?
What happens if it doesn't die?
sleep() method pauses the current thread for a specific time. Isn't that what join() is doing? What's the difference between them?
is join(0) the same as join() ?

It be appreciated if anyone could answer those questions.

Do read the tutorials from the start. When discussing the join method we are dealing with two threads. Join causes the curently executing thread (the one that executed the t.join statement) to pause until the thread t has completed.
The sleep method on the other hand acts on one thread(the currently executing one). That's why it's static while join is not.
Reading the API specs and the tutorials is a must for understanding those things.

API specs?

Surely you've heard of the Java API, right? Thread API

Oh right. Just didn't know what it was called.

t.join() is similar to
wait the main thread till the thread t finishes its work. After finishing a thread comes in terminated state and we call it died.
