Understand SOLID Principle

In this article, I am going to give you brief introduction about SOLID Design principle in Java. The SOLID Design principles represent five design principles that basically used to make the software designs more understandable, flexible and maintainable. The theory of SOLID Design principles was first introduced by Robert C. Martin.

What do you mean by SOLID Design Principles?

The SOLID Design principles are the design principles that basically used to manage most of the software design problems that generally we encountered in our day to day programming. These design principles are provided with some mechanism that will make the software designs more understandable, flexible and maintainable.

SOLID Acronym

  1. S stands for the Single Responsibility Principle.
  2. O stands for the Open-Closed Principle.
  3. L stands for the Liskov Substitution Principle.
  4. I stand for the Interface Segregation Principle.
  5. D stands for Dependency Inversion Principle.

Advantages of SOLID Design Principles

  1. Achieve the reduction in complexity of the code
  2. Increase readability, extensibility, and maintenance
  3. Reduce error and implement Reusability
  4. Achieve Better testability
  5. Reduce tight coupling

In the next article, we will discuss the single responsibility principle with a real-time example. Here, in this article, I try to explain the basics of the SOLID Principle. I hope you understood the need for the Solid Principles.

Now we are going to start with Single Responsibility Principle.
