What is ExecutorService in Java?
ExecutorService is an interface in Java that provides a higher-level replacement for managing threads. It simplifies thread management and allows you to execute tasks asynchronously.
How does it differ from using threads directly?
Using ExecutorService abstracts the thread management, allowing you to focus on task execution rather than thread lifecycle. It handles thread pooling and task scheduling for you.
Can you give me an example of how to use it?
Sure! You can create an ExecutorService instance using Executors.newFixedThreadPool(int nThreads) and submit tasks using the submit() method.
What are the benefits of using ExecutorService?
The benefits include better resource management, easier task scheduling, and improved performance through thread pooling.
