What is a Java Thread Pool and how does it work?

A Java Thread Pool is a collection of threads that can be reused to execute tasks, improving performance by reducing the overhead of thread creation.

Why should I use a Thread Pool instead of creating new threads for each task?

Using a Thread Pool helps manage resources efficiently, reduces latency, and avoids the overhead of creating and destroying threads repeatedly.

Can you explain how to implement a Thread Pool in Java?

Sure! You can use the ExecutorService interface and its Executors factory methods to create a Thread Pool. For example, Executors.newFixedThreadPool(int nThreads) creates a pool with a fixed number of threads.

What are the different types of Thread Pools available in Java?

Java provides several types of Thread Pools, including Fixed Thread Pool, Cached Thread Pool, Single Thread Executor, and Scheduled Thread Pool, each serving different use cases.
