Privious to this video if I wanted to create an integer I would declare it like so. java int someInteger = 0; But now we are doing java Integer someInteger = 0; Is it because of the object we are returning? java public Map getSomeMap(){...}

Yes, you cannot use primitives in Generic type declarations. So a wrapper class is used to autobox (https://docs.oracle.com/javase/tutorial/java/data/autoboxing.html).

Why are we now using Integer instead of int?

Privious to this video if I wanted to create an integer I would declare it like so.

int  someInteger = 0;

But now we are doing

Integer  someInteger = 0;

Is it because of the object we are returning?

public Map<String, Integer> getSomeMap(){...}
