What is the advantage of using Executors over conventional threading? Can anyone explain with a simple example?

Find a copy of Java Concurrency in Practice by Brian Goetz, Tim Peierls, Joseph Bowbeer, David Holmes, Joshua Bloch, Doug Lea.

I think this thread would sit better in the threads forum, so I shall move it.

Executors is a threadpool.
Its costly to create a new thread everytime to process a task.
Its effective and recommended to reuse threads if possible.
Executors do just that for you.

This is the basic benefit of using Executors over thread creation per task.

For detailed discussions do read the book that Campbell has pointed out!
