Hi, In this Covariant example, At Line # 12, Are we getting Line#7 return type "Integer" (or) Line#8 return type "int" ("i" is of int type) ?

The return type of the method is Integer, so that is what is returned. In this case, i is autoboxed. The main method expects an Integer and that's what it's getting.

Try this code. It prints the class of the returned object.
