Liskov Substitution Principle
The Liskov Substitution Principle is a component of The SOLID Principles which helps you create maintainable and extensible code. This principle states that any class should be able to be substituted for any of its subclasses without any issues. This … Click to read more
Open-Closed Principle
The Open-Closed Principle is a component of The SOLID Principles. These principles can help you write software that is easy to extend and maintain whilst also avoiding code smells and bad design in your codebase. The open-closed principle states … Click to read more
Single Responsibility Principle (SRP)
The Single Responsibility Principle (SRP) is one of the aspects of The SOLID Principles. It states that every class or object should have one purpose, one responsibility and effectively one reason for existence. This principle is concerned mainly with … Click to read more
The SOLID Principles
The SOLID principles are a set of 5 rules to follow for Object-Orientated Programming (OOP). These rules or principles can be used to create software that is easy to extend and maintain while avoiding code smells and allowing simple refactoring. … Click to read more
Interfaces and Abstract Classes
Interfaces and abstract classes are used within object orientated programming to extend other classes and add additional functionality without rewriting or duplicating code. The difference between interfaces and abstract classes when compared to creating a normal base class is that … Click to read more
Inheritance and Polymorphism
Inheritance is way to base one class on another class, like a template built from an existing template. You could create a class called ‘Dog’ that acts as a template for all Dog objects. We could then create another class … Click to read more
Classes and Objects
A class is a template used to create objects within code. Classes are the
foundational elements of Object Orientated Programming (OOP). Imagine like a blueprint for a house, the blueprint isn’t a house but is used to create a house … Click to read more
