  • What is a real life example of an abstract class and interface?

    The Animal is the abstract class and Duck/Pig/Cat are all classes that derive from that base class. Animals might provide a function called "Age" that adds 1 year of life to the animals. It might also provide an abstract method called "IsDead" that, when called, will tell you if the animal has died.18 nov. 2009

  • What is an example of an abstract class in real life?

    A concrete example of an abstract class would be a class called Animal. You see many animals in real life, but there are only kinds of animals. That is, you never look at something purple and furry and say "that is an animal and there is no more specific way of defining it".22 sept. 2013

  • What is an example of an interface in real life?

    The Interface is a medium to interact between user and system devices. For example, in our real life, if we consider the interface to be given as an example is the air condition, bike, ATM machine, etc.
  • If you need to provide a base for a hierarchy of classes or provide a common implementation, you should use abstract classes. If you need to define behavior that can be implemented by multiple unrelated classes, you should use interfaces.
