A Java Class must be declared as Abstract in order for it to inherit methods from another one or else it won’t compile. If a certain class declares that it will only have its own custom code, then there should be no need for inheritance at all.
This means that classes declaring themselves as implementing interfaces are generally considered good practice because they can be reused without having to duplicate any codes in different places of the program – which would violate object oriented programming principles such as encapsulation and abstraction.”
