The Main class demonstrates how the AreaCalculator can be used to calculate the total area of different shapes.īy adhering to the Open-Closed Principle, the AreaCalculator class can be extended to support new shape types by adding new classes that implement the Shape interface, without needing to modify the existing code. ![]() This class can easily accommodate new shape implementations without needing to modify its existing code. It iterates over the shapes and calculates the total area by calling the calculateArea() method on each shape. It has a method calculateTotalArea() that accepts an array of Shape objects. The AreaCalculator class demonstrates the Open-Closed Principle by being open for extension but closed for modification. The Circle and Rectangle classes implement the Shape interface and provide their own implementations for the calculateArea() method. In this example, we have an interface called Shape that defines a method calculateArea() for calculating the area of different shapes. Here’s a Java example illustrating the Single Responsibility Principle (SRP): public class Order ĪreaCalculator calculator = new AreaCalculator() ĭouble totalArea = calculator.calculateTotalArea(shapes) This principle encourages a modular design where each class has a clear purpose, leading to improved code readability and maintainability. By focusing on a single responsibility, we ensure that our classes remain highly cohesive and less prone to modification. The Single Responsibility Principle states that a class should have only one reason to change. In this article, we will explore the SOLID principles in depth, highlighting their significance in building robust and maintainable software systems. Importance of SOLID Principles in Software Development.
