Hi,

I have a doubt...

I have a class A, which has 6 methods . two of showing unchecked warnings (generics).
I need to use




Is it good to use 'SuppressWarnings' for the two methods individually or declare 'SuppressWarnings' for the entire class....?

Regards,
Manjusha

It's a good idea to keep the scope of the annotation as small as possible: put it only on the methods (or even the statements inside the method) where it's needed, and not on the entire class.

In fact, it's better to not use that annotation at all - see if there is a way to rewrite your code so that you don't have any unchecked casts in it. Only if there's no way to rewrite the code, use the annotation.
