What is the purpose of the Executor component in task management in Java?

The Executor component in Java is responsible for managing the execution of tasks (Runnable or Callable) in a separate thread or thread pool. It abstracts the creation and management of threads, allowing developers to simply submit tasks for execution.

Main features:

• Allows asynchronous task execution.
• Manages a thread pool, which improves performance and reduces overhead of thread creation.
• Provides a convenient API for starting, canceling, and controlling tasks.

Example of using ExecutorService:

import java.util.concurrent.*;

ExecutorService executor = Executors.newFixedThreadPool(2);

executor.submit(() -> {
    System.out.println("Executing task in a separate thread");
});

executor.shutdown();

Thus, Executor simplifies parallel programming and enhances thread management efficiency.
