Refactoring to SOLID Java SE 17 Code

by Dan Geabunea

This course will teach you how to practically apply SOLID principles in Java SE 17 applications to avoid technical debt and build robust, loosely coupled systems that can evolve easily over time.

What you'll learn

In this course, Java SE 17 Refactoring SOLID Code, you’ll learn to refactor applications by applying SOLID object oriented principles in order to make them more robust and easy to maintain. First, you’ll explore the Single Responsibility Principle and why this is probably the most important 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 find out 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’re finished with this course, you’ll have the skills and knowledge of building code that respects the SOLID principles needed to build loosely coupled applications that are easy to understand, evolve, and maintain.
