Learn Java from Scratch - A Beginner's Guide - Step 06 - Introducing Java Interface to Make App Loosely Coupled

The video tutorial introduces the concept of loose coupling using interfaces in Java. It explains how to refactor a game runner class to interact with a gaming console interface, allowing different game classes like Super Contra and Mario to implement this interface. The tutorial demonstrates the benefits of this approach, such as easier switching between games without modifying the game runner class. An exercise is provided to create a Pac-Man game, reinforcing the concepts learned.
