Hi @Narayan_khanna ,
Yes, the Badge class can be made into an abstract class. It depends on the level of detail you want to go in your design. It is also possible you make a BadgeType enumeration to record whether it’s Gold , Silver , or Bronze . Design problems don’t have a definite solution. We can always tweak them based on our understanding and of course, the requirement set.
Happy Learning
