What is the difference between a thread pool and an executor service?

A thread pool is a collection of pre-initialized threads that can be reused for executing tasks, while an executor service is an interface that provides a higher-level replacement for managing threads and task execution.

Can you explain how an executor service works?

Sure! An executor service manages a pool of threads and allows you to submit tasks for execution. It handles the lifecycle of threads, including their creation, execution, and termination.

When should I use a thread pool instead of creating new threads?

Using a thread pool is more efficient for managing resources, especially when you have many short-lived tasks. It reduces the overhead of thread creation and destruction.

Are there any downsides to using a thread pool?

Yes, if the pool size is too small, it can lead to task starvation. Conversely, if it's too large, it can consume excessive resources.
