Inheritance is the concept which deals with

Inheritance is a fundamental concept in object-oriented programming. It deals with the ability of one class (child class) to inherit the properties (like variables and methods) of another class (parent class). This concept allows for code reusability and the ability to add new features to existing code without modifying it.

Here are the steps to understand it:

1. Define a Parent Class: The parent class, also known as the superclass or base class, is the class whose properties are inherited. It defines certain properties like variables and methods that will be common to all the child classes.

2. Define a Child Class: The child class, also known as the subclass or derived class, is the class that inherits properties from the parent class. It can also define its own unique properties.

3. Use the 'extends' keyword: In many programming languages like Java, the 'extends' keyword is used to denote inheritance. The child class extends the parent class.

4. Access Parent Class Properties: The child class can access (and often override or extend) the properties of the parent class. This is done using the 'super' keyword.

5. Create Objects: Once the classes are defined, you can create objects from the child class. These objects will have access to both the properties of the child class and the parent class.

Remember, the idea behind inheritance is to create a hierarchy of classes that can share code, making it easier to maintain and update.
