In this section, we will look into the Executor interfaces and their implementations provided in the java.util.concurrent package. They encapsulate thread management and minimize the time an application developer spends on the writing code related to threads' life cycles.
There are three Executor interfaces defined in the java.util.concurrent package:
- The base Executor interface has only one void execute(Runnable r) method in it. It basically replaces the following:
Runnable r = ...;(new Thread(r)).start()
However, we can also avoid a new thread creation by getting it from a pool.
- The ExecutorService interface extends Executor and adds four groups of methods that manage the life cycle of the worker threads and of the executor ...
