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.

Polymorphism is the ability of an object to take on different forms or behave in different ways depending on the context in which it is used. In object-oriented programming (OOP), polymorphism is achieved through the use of inheritance, interfaces, and method overloading.

There are two main types of polymorphism in OOP: compile-time polymorphism and runtime polymorphism.

  • Compile-time polymorphism is achieved through the use of method overloading. Method overloading allows a class to have multiple methods with the same name, but with different parameters. The compiler will determine which method to call based on the arguments that are passed to the method.
  • Runtime polymorphism is achieved through the use of inheritance and method overriding. Method overriding allows a subclass to provide its own implementation of a method that is already provided by its superclass. The method that is actually called will be determined at runtime, based on the type of object that is being used.

Polymorphism enhances flexibility in OOP by allowing objects to be used in different ways, depending on their type. This can make code more versatile and reusable. For example, a Shape object can be used to represent any type of shape, such as a circle, square, or triangle. This is because the Shape class has a method called draw() that can be used to draw any type of shape.

Here are some examples of how polymorphism can be used to enhance flexibility in OOP:

  • A Shape object can be used to represent any type of shape. This is because the Shape class has a method called draw() that can be used to draw any type of shape.
  • A Car object can be used to represent any type of car, such as a sedan, SUV, or truck. This is because the Car class has a method called drive() that can be used to drive any type of car.
  • A User object can be used to represent any type of user, such as a customer, employee, or administrator. This is because the User class has a method called login() that can be used to login as any type of user.
