I want to learn to write a thread pool in Java
Can anyone point me to useful resources ?
回答1:
You could have a look at the source code for ThreadPoolExecutor from core java. Though why do you want to reinvent the wheel?
回答2:
take a look at Doug Lea's books... they are fairly old now (unless he released a new one, not sure), but the concurrent package added in 1.5 is based on his threading libraries. as far as i am concerned, he is the authority on concurrent programming in java... his books will give you the basics of what you need to understand to accomplish this task.
i can only assume this is an academic exercise... if not, i would strongly recommend you stick to the concurrent package as it is well-tested and well-developed... don't re-invent the wheel. good luck.

I definitely recommend reading "concurrency in practice". It's the number one book dealing with threading issues in Java.

I agree that re-inventing wheel is not required and we should stick to Executor framework. But even i was curious to know how thread pool is implemented in Executor framework.
found this interesting link which talks how thread pool can be implemented in custom way using threads : http://www.ibm.com/developerworks/library/j-jtp0730/index.html
