Solid Open Closed Principle Example

Ever hear about the Open Closed principle which says components should be open for extension but closed for modification? Well, it’s a very simple idea, but it’s easier to understand if you have a code example or two.

In this case we’ll use Java code, but the same concepts apply for Python, JavaScript, Rust, GoLang and any other computer programming language.
