abstract class and interface real life example

An interface can be used to define a contract behavior and it can also act as a contract between two systems to interact while an abstract class is mainly used to define default behavior for subclasses, it means that all child classes should have performed the same functionality.

What is an example of an interface in real life?

An interface is a programming structure/syntax that allows the computer to enforce certain properties on an object (class).
For example, say we have a car class and a scooter class and a truck class.
Each of these three classes should have a start_engine() action.

What is a real life example of abstraction?

Abstraction in Real Life
Your car is a great example of abstraction.
You can start a car by turning the key or pressing the start button.
You don't need to know how the engine is getting started, what all components your car has.
The car internal implementation and complex logic is completely hidden from the user.

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

Real-time Example of abstraction in java
Suppose we have Sport as an interface.
Here, implementation will be provided by classes called “Badminton” and “Football”.
In a real scenario, an end user will not be aware of the implementation class._{10 jan. 2019}

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".
