Solid Principles Tutorials with Java Coding Example for Beginners

In this video, we will discuss the SOLID principles for object-oriented programming and design. what is the purpose of Solid Principle in software design and development? First, we'll understand the reasons why we need SOLID principle in our software design consideration. Then we'll discuss each principle in details with real world example and code. The SOLID principles were first introduced by the famous Computer Scientist sir Robert J. Martin also known as Uncle Bob in his paper in 2000. But the SOLID acronym was introduced later by Michael Feathers. They explained the reasons why we should take SOLID principle in to consideration while designing a software. They explained how SOLID principles influence us to create more maintainable, understandable, and flexible software. As our applications grow in size so as the complexity hence SOLID principles are useful in reducing the complexity and maintaining applications. All these concepts and patterns serves the same purpose i.e. "To create understandable, readable, and testable code that many developers can collaboratively work on." ** Solid Principles Introduction ** Eventually, as our applications grow in size so as the complexity hence, we need SOLID principle to reduce the complexity and to maintain an application. These principles establish practices that lend to developing software with considerations for maintaining and extending as the project grows. Adopting these practices can also contribute to avoiding code smells, refactoring code, and Agile or Adaptive software development. The SOLID Principles are five principles of Object-Oriented class design. They are a set of rules and best practices to follow while designing a class structure. These five principles help us understand the need for certain design patterns and software architecture in general. So, I believe that it is a topic that every developer should learn. This principle is an acronym of the five principles which is given below… 1. The Single Responsibility Principle - a class should do one thing and therefore it should have only a single reason to change. 2. The Open-Closed Principle - The classes should be open for extension and closed to modification. 3. The Liskov Substitution Principle - The derived or child classes must be substitutable for their base or parent classes. 4. The Interface Segregation Principle - means keeping things separated and larger interfaces should be split into smaller ones. 5. The Dependency Inversion Principle - Interface or abstract class should not depend on child classes instead child classes should depend upon interfaces or abstract classes. In software development, Object-Oriented Design plays a crucial role when it comes to writing flexible, scalable, maintainable, and reusable code. There are so many benefits of using OOD but every developer should also have the knowledge of the SOLID principle for good object-oriented design in programming. ** Where to use Solid Principles** 1. Use solid principle if you want to build maintainable, scalable, testable, and reusable software application. 2. Use solid principle if you are using object-oriented programming language and design. 3. Use solid principle where code is written and modified by people, organized into modules, and contains internal or external elements. ** Advantages of Solid Principles** 1. The goal of SOLID principles is to reduce code dependencies, and adding a new feature or changing a part of the code doesn't break the whole build. 2. Using SOLID principles in object-oriented design makes the code easier to understand, manage, maintain, and change. 3. The SOLID principle helps in reducing tight coupling. Tight coupling means a group of classes are highly dependent on one another which you should avoid in your code. your code is considered as a good code when it has loosely-coupled classes. Loosely coupled classes minimize changes in your code, helps in making code more reusable, maintainable, flexible and stable. 4. SOLID provides sound design principles applicable to modern programs and environments, not just object-oriented programming. ** Topics Covered ** 1. Introduction of Solid Principles 2.
