public class ThreadPool

extends Object

A simple thread pool. Idle threads are cached for future use. The cache grows until it reaches a maximum size (default 10). When there is nothing in the cache, a new thread is created. By default the threads are daemon threads. Rickard Öberg Adrian Brock Jeff Haynie
