ExecutorService in Java Explained | Thread Pool + Top Interview Questions

Description: In this video, we understand ExecutorService and Thread Pools in Java with a practical example and then cover commonly asked Java interview questions.

We start with a simple question: If you have 100 tasks, would you create 100 threads?

You'll learn how a thread pool allows us to reuse a limited number of threads to execute multiple tasks efficiently.

Topics covered:

* What is ExecutorService?
* What is a Thread Pool?
* Why do we use Thread Pools?
* Creating a Fixed Thread Pool
* execute() vs submit()
* Future and ExecutorService
* Runnable vs Callable
* What happens when 100 tasks are submitted to 5 threads?
* shutdown() vs shutdownNow()
* Task execution order
* Common ExecutorService interview questions
* Future vs CompletableFuture

This video is useful for Java, Spring Boot and Backend Developer interviews.
