What is the difference between Java threading and asynchronous programming?

What is the difference between Java threading and asynchronous programming?

Java threading involves creating multiple threads to execute tasks concurrently, while asynchronous programming allows tasks to run without blocking the main thread.

Can you give me an example of when to use threading?

You might use threading for tasks like handling multiple client requests in a server application, where each request can be processed in a separate thread.

And what about asynchronous programming? When is it more beneficial?

Asynchronous programming is beneficial for I/O-bound tasks, like reading files or making network requests, where you want to avoid blocking the main thread.

Are there any performance differences between the two?

Yes, threading can lead to overhead due to context switching, while asynchronous programming can be more efficient for I/O-bound tasks as it minimizes blocking.
