Understanding Generics

Hey guys! As always, thank you in advance for your help!

I am triying to understand exactly what generics are used for.

As I understood, is just to avoid having other types of objects being the parameter of a method that is not ready to handle them, right?

Apart from that, is there anything else? Am I missing something here? (I think I am!)

A couple of simple examples would really help here :)

This YouTube video helped me understand it a little better myself

EDIT: for thinking of <> as 'of' then in this example Glass<Juice> & Glass<Water> would be 'glass of juice' and 'glass of water' respectively
