Java / Java Multithreading

Define Java thread pool.

Java Thread pool is a group of worker threads that are waiting for the tasks to be assigned and be reused again. Worker threads return to the thread pool after it completes its task.

A group of fixed size threads are created in the thread pool. A thread from the thread pool is chosen and assigned a runnable task by the service provider. After completion of the job, thread is returns to the thread pool.

java.util.concurrent.Executors provide implementation of java.util.concurrent.Executor interface to create the thread pool in java.
