When should I use async in Java?

When should I use async in Java?

You should use async in Java when you want to improve the responsiveness of your application, especially in I/O-bound tasks.

Can you give me an example of an I/O-bound task?

Sure! An example of an I/O-bound task is reading data from a file or making a network request. These tasks can benefit from async to avoid blocking the main thread.

What are the benefits of using async over synchronous programming?

The main benefits include improved performance, better resource utilization, and enhanced user experience by keeping the application responsive.

Are there any downsides to using async?

Yes, async programming can introduce complexity, such as callback hell and difficulty in debugging, so it should be used judiciously.
