What are Java Executors and how do they work?

Java Executors are part of the Java Concurrency framework that simplify the execution of asynchronous tasks. They manage a pool of threads and allow you to run tasks without having to manage the threads manually.

Can you explain the different types of Executors available in Java?

Sure! The main types of Executors in Java are: 1. FixedThreadPool - a pool with a fixed number of threads. 2. CachedThreadPool - creates new threads as needed and reuses previously constructed threads. 3. SingleThreadExecutor - a single-threaded executor that ensures tasks are executed sequentially.

How do I create a FixedThreadPool in Java?

You can create a FixedThreadPool using the Executors class like this: ExecutorService executor = Executors.newFixedThreadPool(n); where n is the number of threads you want in the pool.

What are the advantages of using Executors over manually managing threads?

Using Executors simplifies thread management, improves resource utilization, and provides better control over task execution, making your code cleaner and more efficient.
