Solid Principles - Project example

 Solid Principles - Project example

Single Responsibility Principle

your code should have only one job - Mail and SMS

Open/Closed Principle

We can override the class functionality, but not change the existing class. Abstract -> Overide. Example - Version Maintain

Liskov/Substitution Principle

Derived class must be substitutable for its base class.

Abstract Class -> Interface -> No Override method

Use Abstract class in interface and give more explanation

Interface Segregation Principle

clients should not be forced to implement interfaces they don't use. Instead of one fat interface, many small interfaces are preferred.

     

Dependency Inversion Principle

high-level modules/classes should not depend on low-level modules/classes. should depend upon abstractions.

Use dependency injection for injecting the dependency
