The Executors class in Java provides factory and utility methods for the Executor, ExecutorService, ScheduledExecutorService, ThreadFactory, and Callable classes defined in the java.util.concurrent package. It helps in creating thread pools and managing asynchronous task execution.
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() | Converts a Runnable into a Callable that returns the specified result. |
| 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 available. |
| newFixedThreadPool() | Creates a thread pool that reuses a fixed number of threads operating off a shared unbounded queue. |
| 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 starts a new virtual thread for each task. |
| newWorkStealingPool() | Creates a work-stealing thread pool using all available processors as its target parallelism level. |
The Executors class in Java simplifies thread management and asynchronous task execution, providing various methods to create and manage different types of thread pools efficiently.
