The Law of Demeter (LoD), or Principle of Least Knowledge, is a design guideline in object-oriented programming that promotes loose coupling. It states that an object should only interact with its immediate collaborators, avoiding method chains (e.g., obj.getA().getB().getC()). Following LoD improves encapsulation, maintainability, and modularity. Read more about Law of Demeter.

Let’s be honest, often times we have to break the Law of Demeter. In this article, we will discuss how to break the Law of Demeter gracefully in Java.
