📄️ What is SOLID
SOLID is an acronym for five principles of object-oriented programming (OOP) that are designed to improve the design and maintainability of software. The principles are:
📄️ The Single Responsibility Principle (SRP)
The Single Responsibility Principle (SRP) is a principle of object-oriented programming (OOP) that states that a class
📄️ Open/Closed Principle (OCP)
What is OCP?
📄️ Liskov Substitution Principle (LSP)
The Liskov Substitution Principle (LSP) is a principle of object-oriented design that states that objects in a program should be replaceable with instances of their subtypes without affecting the correctness of the program. In other words, if a class is a subtype of another class, then objects of the subtype class should be able to be used wherever objects of the parent class are used without causing any problems. This allows for flexibility and maintainability in object-oriented design, as well as code reusability and extensibility. To implement the LSP, developers can use techniques such as polymorphism and inheritance.
📄️ Interface Segregation Principle (ISP)
The Interface Segregation Principle (ISP) is a principle of object-oriented design that states that no client should be forced to depend on methods it does not use. This means that classes should have small, specific interfaces that only include the methods that are actually needed by the client classes. This allows for better code organization and maintainability, as well as flexibility to accommodate future changes in requirements. To implement the ISP, developers can use techniques such as abstraction and composition.
📄️ Dependency Inversion Principle (DIP)
The Dependency Inversion Principle (DIP) is a principle of object-oriented design that states that high-level modules should not depend on low-level modules, but rather both should depend on abstractions. This means that instead of directly depending on concrete implementations of classes, modules should depend on abstract interfaces or contracts. This allows for better code organization and maintainability, as well as flexibility to accommodate future changes in requirements. To implement the DIP, developers can use techniques such as abstraction, inversion of control, and dependency injection.
