Java Keywords (Part XII): Implementing Interfaces and Extending Classes

We are up to 34 keywords covered in previous articles! That's 71% keywords covered. We have only 16 keywords to cover and I will be covering 2 of those in this article. This article will illustrate the use of the keywords implements and extends for implementing functionality outlined in interfaces as well as extending the functionality of a class. I suggest you start with Java Keywords (Part I) before proceeding further, if you have not read any of the previous articles in the Java Keyword series. Also, go back and read the one about Data Types. All of these articles are from September 2018. That should help you find them quickly. You can also use the "search" option at the top of this page. The series was written with natural progression in mind. Therefore, some of the keywords already covered may be used in code examples illustrated here.
