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.
 
It is sorta covered in the JavaRanch Style Guide.
