SOLID Programming Principles

This week I wanted to take a look at five principles of object oriented programming, known as the SOLID principles, and write about practical applications of each.

Single Responsibility Principle — An object should only serve one purpose.

Open/Closed Principle — An object should be open to extension, but closed for modification.

Liskov Substitution Principle — objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program

Interface Segregation Principle — Many specific interfaces are better than one generic interface

Dependency Inversion Principle — Design to the interface, not the implementation.

I’ll be taking a more in-depth look at each of these this week.
