The Optional concept is present in many programming languages. The main goal of the Optional class is to avoid NullPointerException. It’s much easier to deal with null values when we use the concepts of an Optional.
In this challenge, we will also explore the takeWhile and dropWhile methods from Java 9. Therefore you will be upgrading your knowledge with Optional, takeWhile, and dropWhile!
Are you prepared to have fun with this Java Challenge and refine your Java skills?
