Java Programming for Complete Beginners - Java 16 - Step 03 - Functional Programming - Exercise - Loop a List of Numbers

The video tutorial introduces an exercise on creating a list of numbers and printing them using functional programming in Jshell. It guides viewers through creating a list of integers, using streams and lambda expressions to print each element, and executing code without traditional loops. The tutorial concludes with a preview of more complex functional programming topics.
