  1. Single Responsibility Principle: A class should have only one reason to change, meaning it should have only one responsibility.
  2. Open-Closed Principle: The O in SOLID stands for Open-Closed Principle. This concept states that a class or state can be open for extension and closed for modification. 
  3. Interface Segregation Principle: A client shall not depend on the interfaces they don't use. 
  4. Dependency Inversion Principle: The dependencies can be abstract and not specific. 

You can know if your Java Developers understand OOPS in SOLID if they grasp the concepts theoretically and practically.
