Earlier, I have shared the best Java Programming courses, and today, I am going to review Java Programming Masterclass for Software Developers by Tim Buchalka, one of the highest-rated Java courses from Udemy. This course was also known as The Complete Java Masterclass before and now its known as Java 17 Masterclass: Start Coding in 2025. I have mentioned this course multiple times throughout different articles because it's currently the best course to learn Java.

Strategy Design Pattern and Open Closed Principle in Java - Example

Strategy design pattern is based upon open closed design principle, the 'O' of famous SOLID design principles. It's one of the popular pattern in the field of object-oriented analysis and design along with Decorator, Observer and Factory patterns. Strategy pattern allows you to encapsulate possible changes in a process and encapsulate that in a Strategy class. By doing that your process (mainly a method) depends upon a strategy, higher level of abstraction than implementation. This makes your process open for extension by providing new Strategy implementation, but closed for modification, because the introduction of a new strategy doesn't require a change in a tested method. That's how it confirms open closed design principle.
