Pass additional data in an exception?

Question

Java

Is it possible to create your own CustomException and pass additional variables (int long etc) to it for processing in the catch block?
Is this practiced or should it be avoided?

Answer 1

If you use such a CustomException exclusively inside your application, and your application does not have a public API through which such an exception can be thrown, then I see nothing wrong with using a CustomException.

Answer 2

Can. That's what the exception object is for.

Answer 3

This is best avoided
