OOPS, Interface, Why to use interface, how to implement run time polymorphism, real time example of interface

Question

Accepted Answer

Interface in OOPS is used to achieve abstraction and multiple inheritance. It allows for run time polymorphism by implementing methods in different classes.

Interface in OOPS is a blueprint of a class that includes abstract methods without any implementation.
Interfaces are used to achieve abstraction, multiple inheritance, and loose coupling in code.
To implement run time polymorphism using interfaces, create multiple classes that implement the same interface and override its methods.
Real-time example of interface: A car interface with methods like start(), stop(), accelerate(). Different car classes like Sedan, SUV, and Hatchback can implement this interface and provide their own implementation of these methods.
