A class is a user-defined blueprint or prototype from which objects are created. Classes provide a means of bundling data and functionality together. Creating a new class creates a new type of object, allowing new instances of that type to be made. Each class instance can have attributes attached to it for maintaining its state. Class instances can also have methods (defined by its class) for modifying its state.

Accessing Parent Class Functions
When a class inherits from another class it inherits the attributes and methods of another class. A class that inherits from another class is known as child class and the class from which the child class inherits is known as Parent class. But have you ever wondered how to access the parent’s class methods? This is really simple, you just have to call the constructor of parent class inside the constructor of child class and then the object of a child class can access the methods and attributes of the parent class.

Accessing Parent class method from inner class
An inner class or nested class is a defined inside the body of another class. If an object is created using a class, the object inside the root class can be used. A class can have one or more than one inner classes.
Types of Inner Classes:
- Multiple Inner Class
- Multilevel Inner Class
Multiple Inner Class: A class containing more than one inner class.
