SOLID class design principles
Explore the SOLID design principles that help create maintainable, flexible classes in object-oriented programming. Understand each principle, including Single Responsibility and Dependency Inversion, to improve your Java code's structure and ease of testing. This lesson guides you in applying these concepts for cleaner, more reusable class designs aligned with unit testing best practices.

In the mid-1990s, Robert C. Martin gathered five principles for object-oriented class design, presenting them as the best guidelines for building a maintainable object-oriented system. Michael Feathers attached the acronym SOLID to these principles in the early 2000s.
- Single Responsibility Principle (SRP): Classes should have one reason to change. Keep classes small and single-purposed.
