java - Check if two ArrayLists accept the same class (same generic) -

-

if have 2 empty arraylists, how can check if accept same class of object.

the function like, 

    public boolean havesametype(arraylist array1, arraylist array2){ ... }'

in general case, want able compare generics of 2 objects in class.

edit:

in specific case have abstract class

    public abstract class dog<e extends cat> { ... }

and trying compare 2 objects know of class dog (or subclass obviously). cannot 

    dog adog //gives warning because dog should parameterized

so correct way create variable?
