The purpose of extending a class in inheritance in object-oriented programming is to create a new class that inherits the properties and methods of the existing class. This concept is used for the following reasons:

1. **Code Reusability**: Inheritance allows us to reuse the code, it improves reusability in your java code.

2. **Method Overriding**: The subclass can provide a specific implementation of a method that is already provided by its parent class or superclass.

3. **Code Optimization**: It makes programmers write clear and manageable code, which helps to maintain and enhance the program.

4. **Hierarchy Creation**: You can use inheritance to create a hierarchy of classes that can represent real-world objects.

5. **Polymorphism**: It is a concept by which we can perform a single action in different ways. We can perform polymorphism in java by method overloading and method overriding.

So, extending a class in inheritance helps in increasing the functionality of the class without modifying it, which leads to a better organization of code and easier maintenance.
