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

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

A thread pool is a collection of pre-initialized threads that can be reused for executing tasks, while an executor is an interface that provides a way to manage and control the execution of asynchronous tasks.

Can you explain how a thread pool improves performance?

Sure! A thread pool improves performance by reducing the overhead of thread creation and destruction, allowing tasks to be executed more quickly by reusing existing threads.

When should I use an executor instead of a thread pool?

You should use an executor when you need a higher-level abstraction for managing task execution, as it provides more flexibility and control over task scheduling and execution.

Are there any downsides to using a thread pool?

Yes, potential downsides include resource contention if too many tasks are submitted, and the risk of thread starvation if tasks take too long to complete.
