The Object-Oriented Design Principles are the core of OOP programming, but I have seen most of the Java programmers chasing design patterns like Singleton pattern, Decorator pattern or Observer pattern, and not putting enough attention on learning Object-oriented analysis and design. It's important to learn basics of Object-oriented programming like Abstraction, Encapsulation, Polymorphism, and Inheritance. But, at the same time, it's equally important to know object-oriented design principles, to create the clean and modular design. I have regularly seen Java programmers and developers of various experience level, who either don't hear about these OOP and SOLID design principle, or simply doesn't know what benefits a particular design principle offers, or how to apply these design principle in coding.
