What are the benefits of using a thread pool in Java over creating new threads?

Using a thread pool in Java can improve performance by reusing existing threads, reducing the overhead of thread creation.

Can you explain how thread pools manage threads?

Thread pools maintain a set of worker threads that can be reused for executing tasks, which minimizes the cost of thread management.

What happens if all threads in the pool are busy?

If all threads are busy, new tasks can be queued until a thread becomes available, preventing resource exhaustion.

Are there any downsides to using thread pools?

Yes, if the pool size is too small, it can lead to delays in task execution. Conversely, a very large pool can waste resources.
