Answer 2

Wrapper classes are the name of those classes used for the boxing (turning a primitive variable into an object) process.

You should be able to understand the benefits right after you get the advantages of objects (references) over primitives on any Object Oriented Programming course here.

I would suggest Java or C#.

Good luck Ali.
