I'm trying to find some useful cases for reflection on my own and i've just discovered an interesting thought from this post: it says,

say you have an object of an unknown type in Java

Can you provide a couple of examples of that with a plain English explanation?

For example, if you want to write a method which serializes any `Object` to `json` or `xml` – Arnaud Denoyelle Jul 29 '17 at 12:51

Unknown type such as you only know it `extends Object` but don't know what it is. – EpicPandaForce Jul 29 '17 at 12:51
Oh yes, makes sense. i was overthinking this badly. – Jul 29 '17 at 12:53
