How do you modify existing classes and objects?
Object oriented design (OOD) is a way of designing software systems based on the concepts of classes and objects. Classes are blueprints that define the attributes and behaviors of a group of similar objects, while objects are instances of classes that have specific values and can interact with other objects. OOD allows you to create modular, reusable, and maintainable code that can adapt to changing requirements. But how do you modify existing classes and objects when you need to add new features, fix bugs, or improve performance? In this article, we will discuss some common principles and techniques for modifying classes and objects in OOD.
