How do Java Futures and Thread Pools work together?

Can you explain how Java Futures and Thread Pools work together?

Sure! Java Futures represent the result of an asynchronous computation, while Thread Pools manage a pool of worker threads.

How do I create a Thread Pool in Java?

You can create a Thread Pool using the Executors class, like this: ExecutorService executor = Executors.newFixedThreadPool(n); where n is the number of threads.

What are the benefits of using Thread Pools?

Thread Pools improve performance by reusing threads, reducing the overhead of thread creation, and managing resources efficiently.

Can you give an example of using Futures with a Thread Pool?

Certainly! You can submit tasks to the Thread Pool and get a Future object to retrieve the result later, like this: Future<Integer> future = executor.submit(() -> { return 1 + 1; });.
