Java Executors Methods

The Executors class in Java is part of the java.util.concurrent package and provides factory methods for creating different types of executor services. These services are used for managing a pool of threads and can be used to execute tasks asynchronously. The Executors class simplifies the creation and management of thread pools.

This guide covers various methods available in the Executors class. Each method is described in simple terms to help beginners understand how to use them. These methods enable the creation of different types of thread pools, each suited for specific use cases, such as fixed thread pools, cached thread pools, and scheduled thread pools.

For more detailed information, please refer to the official Java SE Documentation.

Java Executors Methods

The table below contains various methods of the Java Executors class, each with a link to a detailed explanation, examples, and real-world uses. Click on the method names to learn more about how to use them effectively in your applications.

Method	Description
callable()	Creates a Callable object from a Runnable task.
defaultThreadFactory()	Returns a default thread factory used to create new threads.
newCachedThreadPool()	Creates a thread pool that creates new threads as needed but will reuse previously constructed threads when they are available.
newFixedThreadPool()	Creates a thread pool with a fixed number of threads.
newScheduledThreadPool()	Creates a thread pool that can schedule commands to run after a given delay or to execute periodically.
newSingleThreadExecutor()	Creates an executor that uses a single worker thread operating off an unbounded queue.
newSingleThreadScheduledExecutor()	Creates a single-threaded executor that can schedule commands to run after a given delay or to execute periodically.
newVirtualThreadPerTaskExecutor()	Creates an executor that allocates a new virtual thread for each task.
newWorkStealingPool()	Creates a work-stealing thread pool using all available processors as its target parallelism level.
