I completed my post-graduation in 2013 in the engineering field. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. I love pet animals such as dogs, cats, etc.

Inheritance is a mechanism in object-oriented programming (OOP) that allows a new class to inherit the properties and methods of an existing class. This means that the new class can use the code that is already written in the existing class, without having to reimplement it. This can save time and effort, and it can also help to ensure that the code is implemented consistently.

For example, let's say we have a Vehicle class with a method called start(). This method starts the vehicle. We could then have a Car class that inherits from the Vehicle class. The Car class could use the start() method from the Vehicle class, without having to reimplement it.

Inheritance can also be used to support code reuse in more complex ways. For example, we could have a Shape class with a method called draw(). This method draws the shape. We could then have subclasses of Shape that represent specific types of shapes, such as circles, squares, and triangles. These subclasses could inherit the draw() method from the Shape class, but they could also override the draw() method to provide their own implementation. This would allow each subclass to draw its own type of shape in a unique way.

Inheritance is a powerful tool that can be used to achieve greater code reuse in OOP. It allows programmers to create new classes that are based on existing classes, without having to reimplement the code that is already written. This can save time and effort, and it can also help to ensure that the code is implemented consistently.

Here are some of the benefits of inheritance:

  • Code reuse: Inheritance allows for greater code reuse by allowing new classes to inherit the properties and methods of existing classes.
  • Flexibility: Inheritance can be used to support code reuse in complex ways, such as by allowing subclasses to override the methods of their superclasses.
  • Abstraction: Inheritance can be used to hide implementation details from the user, which can make the code more understandable and maintainable.
