Applying the Open/Closed Principle requires some clever design decisions. One of the common techniques is the use of abstraction and inheritance.
Let's take the example of a graphical shape library. You have different shapes like squares, circles, and triangles, each with its own area calculation logic. Now, instead of modifying each shape class every time we need to add a new shape, we can create an abstract base class called "Shape" with a method called "calculateArea()." Each shape class, like "Square," "Circle," or "Triangle," will inherit from this base class and provide their own implementation of the area calculation method. #youtube #youtubeshorts #ytshorts #syedadeelshafqatofficial
