generics - Is there a difference between explicitly putting the type into the diamond operator vs letting java figure it out?

Question

Is there any difference between initialization via:

MyWrapper<String> wrapper = new MyWrapper<String>();

vs initialization via:

MyWrapper<String> wrapper = new MyWrapper<>();

Is there any reason why one would want to use the former over the latter? I see a lot of the former; I'm not sure if it's just because that's what people are used to, or there's a reason you'd want to write it that way.

Answer 1

The latter is only available since Java 7. That's why you often see the former. The latter is equivalent, and shorter.
