Executor Framework: Introduction | Java Multithreading
The Executor Framework in Java provides a standardized way of asynchronously executing tasks. It decouples task submission from task execution, allowing developers to focus on the logic of the tasks rather than the mechanics of thread management.
Here's a brief overview of the Executor Framework components:
Executor: The main interface of the framework. It represents an object capable of executing submitted Runnable tasks. It abstracts the details of thread creation, management, and monitoring.
ExecutorService: A subinterface of Executor that provides a more complete asynchronous task execution framework. It extends Executor and adds features like task submission, shutdown, and methods to control the status of the execution.
ThreadPoolExecutor: A class that provides an implementation of ExecutorService. It manages a pool of worker threads and a queue of tasks waiting to be executed. ThreadPoolExecutor allows fine-tuning of parameters such as the size of the thread pool, the queue capacity, and thread creation policies.
ScheduledExecutorService: A subinterface of ExecutorService that supports the scheduling of tasks to execute after a given delay or periodically. It provides methods to schedule tasks to run at a specific time or with a fixed delay between executions.
Executors: A utility class that provides factory methods for creating instances of ExecutorService, including fixed-size thread pools, cached thread pools, single-threaded executors, and scheduled executors.
