__________________________________________________________
output
both objects are same
both objects are not same
__________________________________________________________
cover all class member in highlighted condition as per business logic to check object equality
if we cover userid in highlighted condition than we will get obj1 and obj2 are not same object because there exist userid of both objects are different 1 and 2 but we are only concern with user name, so we place only userName in highlighted condition.
