The two classes are unrelated, each can exist without the other one. I interviewed at Quora, Inc. (Mountain View, CA (US)) in November 2019. On the abstract level, you only need to define the method signatures (name and parameter list) and let each class implement them in their own way. One such application revolves around the search for efficient sustainable forms of energy, in this case the use of semiconductors to assist in the conversion of light to electrical energy. Object-oriented programming System(OOPs) is a programming paradigm based on the concept of “objects” that contain data and methods.
