What are the differences between ExecutorService and Thread in Java?

What are the differences between ExecutorService and Thread in Java?

ExecutorService is a higher-level replacement for managing threads. It provides a pool of threads and handles task execution, while Thread is a lower-level construct that represents a single thread of execution.

Can you explain the advantages of using ExecutorService?

Sure! ExecutorService simplifies thread management, allows for better resource utilization, and provides features like task scheduling and future results.

Are there any scenarios where I should use Thread instead?

Yes, if you need fine-grained control over thread behavior or if you're implementing a very simple application, using Thread directly might be appropriate.

How does thread pooling work in ExecutorService?

Thread pooling in ExecutorService reuses a fixed number of threads to execute multiple tasks, reducing the overhead of thread creation and destruction.
