Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.
Inheritance allows code reuse and promotes code organization.
The existing class is called the parent or superclass, and the new class is called the child or subclass.
The child class inherits all the properties and methods of the parent class and can also add its own unique properties...

An interface is declared using the 'interface' keyword.
All methods in an interface are public and abstract by default.
A class can implement multiple interfaces.
Interfaces can also extend other interfaces.
Example: public interface MyInterface { void myMethod(); }
