Mastering Java Stream Map with a Simple Example

I often use the steam().map() functionality in Java from functional programming to apply a function to each element in a list and, therefore, wanted to share my experience. In this video I go through a very simple use case, let me know if you want to see a more real-life-like example.

NOTE: In most of the video, I am using ".collect(Collectors.toList())", which was replaced with the simpler code ".toList()" in Java 16. But they do the exact same thing; old habits die hard.
