Liskov Substitution Principle
Welcome to the third installment of our five-part series on SOLID principles. In this blog, we’ll deep dive into the ‘L’ in SOLID. Get ready to explore the core concept of the Liskov Substitution Principle and discover how it can revolutionize your approach to software development.
The Liskov Substitution Principle (LSP) is one of the SOLID principles of object-oriented design, introduced by Barbara Liskov in 1987. It defines that objects of a superclass should be replaceable with objects of a subclass without affecting the correctness of the program. In simple terms, if a class is a subclass of another class, it should be able to be used wherever its parent class is used, without causing issues.
if a class is a subclass of another class, it should be able to be used wherever its parent class is used, without causing issues.
Mechanisms to Achieve Liskov Substitution Principle:
To adhere to the Liskov Substitution Principle, consider the following mechanisms:
1. Inheritance: Use inheritance to create a subclass that extends the functionality of a superclass while maintaining the same interface. Subclasses should be able to substitute instances of the parent class.
