In Java, SOLID principles are an object-oriented approach that are applied to software structure design. It is conceptualized by Robert C. Martin (also known as Uncle Bob). These five principles have changed the world of object-oriented programming, and also changed the way of writing software. It also ensures that the software is modular, easy to understand, debug, and refactor.
The word SOLID acronym for :
* Single Responsibility Principle (SRP)
* Open-Closed Principle (OCP)
* Liskov Substitution Principle (LSP)
* Interface Segregation Principle (ISP)
* Dependency Inversion Principle (DIP)
