Java Programming for Complete Beginners - Java 16 - Step 15 - Behind the Screens with Functional Interfaces - Implement

The video tutorial explores the map method and its background, focusing on how it processes even numbers to produce their squares. It delves into the concept of functional interfaces, particularly the map interface, and explains how these interfaces work behind the scenes. The tutorial provides a practical example by implementing a square mapper class, demonstrating the application of the function interface. It concludes with an overview of key functional interfaces, including function, predicate, and consumer, highlighting their roles in functional programming.

How does the apply method relate to the functional interface in the context of the map method?
