Whether to use inheritance?

Question

OOP

There is a device class inside which there should be three sockets. Do I need to use the device inheritance from the socket class here? In the example below, it is implemented simply by connecting a file and declaring sockets.

Answer 1

Inheritance is applied if it is possible to say that something is something. For example, a developer is an employee; the computer is a device, and so on.

Ask yourself the question: "Is the device a socket?" and you'll understand right away.
