What's a good example for class inheritance? [closed]

Answer 1

I think Shape is a good abstract class. There are both 2D and 3D shapes. The 2D shapes typically have area while 3D shapes have volume. Both can have a "location" or "mass center".

Some suggestions:

class Shape {..}

class Shape2D extends Shape {...}

class Circle extends Shape2D {...}

class Rectangle extends Shape2D {...}

class Polygon extends Shape2D {...}

class Shape3D extends Shape {...}

class Sphere extends Shape3D {...}
