Refactoring to SOLID Java SE 17 Code

This course will teach you how to practically apply SOLID principles in Java applications to avoid
technical debt and build robust, loosely coupled systems that can evolve easily over time.

In this course, Refactoring to SOLID Java, you’ll learn to refactor applications by applying SOLID object-oriented principles to make them more robust and easy to maintain. First, you’ll explore the Single Responsibility Principle and why this is probably the most crucial concept in programming. Next, you’ll discover the Open Closed principle and learn how to evolve applications without altering existing code. After that, you'll explore the Liskov Substitution Principle and discover how to create correct relationships using inheritance. Then, you'll see why it’s not a good idea to create “fat” interfaces and change that using the Interface Segregation Principle. Finally, you’ll learn how to create loosely coupled components by applying the Dependency Inversion Principle. When you finish this course, you’ll have the skills and knowledge to refactor legacy JAVA projects into systems that respect the SOLID and are easy to understand, evolve, and maintain.
