SOLID Principles
Liskov Substitution Principle (LSP)
The Liskov Substitution Principle states that objects of a superclass should be replaceable with objects of a subclass without affecting the correctness of the program. In other words, if S is a subtype of T, then objects of type T may be replaced with objects of type S without altering any of the desirable properties of the program (correctness, task performed, etc.).
Subtypes must be substitutable for their base types without altering the correctness of the program.
Benefits:
- Ensures that derived classes are properly implementing the behavior expected from the base class.
- Promotes the use of polymorphism correctly.
- Enhances code reliability and robustness.
General Tips!
- Start Small: Begin by applying these principles to new code you write. Gradually refactor existing code to comply with SOLID principles as you work on it.
- Test Often:Test Often: Use unit testing to ensure that your abstractions work correctly and that changes to your code do not introduce new bugs.
- Code Reviews: Incorporate SOLID principles into your code review process. Have peers review your code to ensure adherence to these principles.
- Continuous Learning: Keep learning and improving your understanding of these principles. Read books, articles, and tutorials, and practice applying these concepts in your projects.
