Java.util.concurrent.Executor interface with Examples
The concurrent API in Java provides a feature known as an executor that initiates and controls the execution of threads. As such, an executor offers an alternative to managing threads using the thread class. At the core of an executor is the Executor interface. It refers to the objects that execute submitted Runnable tasks.
