What is the result of a class implementing an interface?

A class implementing an interface must provide definitions for all the methods declared in that interface. This requirement ensures that any object of the class is capable of fulfilling the contract established by the interface.

Interfaces are used to define a set of methods that other classes must implement, promoting a consistent method structure across different classes. By adhering to the interface, the class guarantees that it will have specific behaviors, allowing for polymorphism and improving code flexibility and reusability.

In object-oriented programming, particularly in languages like Java or C#, this principle is crucial in achieving abstraction and multiple inheritance capabilities, where a class can implement multiple interfaces while implementing all their required methods.
