Android Build a Simple Android App (2014) Improving Our Code Simple Refactoring: Using a Class

Can someone explain how does it work that: you can use the class name as the data type for a variable?

i am just not able to get it conceptually. i only find it logic when having Data Types as being int, double, float, String etc. How can the class become a data type for a variable?

A class is a super-data type, the system saves a class for use. Just like it saves Integers and String etc.

Maybe a way to get it is to consider that those simple data types (int, double, float, String) are actually themselves classes except they have been simplified for use.

In essence everything is a class, but we use some classes very often so much they have been simplified so we don't have to go through constructing them each time.
