What is thread pooling and how does it work?

Thread pooling is a technique used in programming to manage a pool of worker threads for executing tasks. Instead of creating a new thread for each task, a fixed number of threads are created and reused, which improves performance and resource management.

What are the benefits of using thread pooling?

The benefits include reduced overhead from thread creation, improved resource utilization, and better performance for applications with many short-lived tasks.

Can you give me an example of thread pooling in Java?

Sure! In Java, you can use the ExecutorService interface to create a thread pool. For example: ExecutorService executor = Executors.newFixedThreadPool(5); This creates a pool of 5 threads.

What happens if all threads in the pool are busy?

If all threads are busy, new tasks will wait in a queue until a thread becomes available to execute them.
