100. Java 8 Features: Understanding forEach, Consumers, and Functional Interfaces

Unlock the power of modern Java by mastering the forEach method!
If you have ever wondered why Java introduced a new way to loop or how to transform chunky blocks of code into sleek Lambda expressions, this video is for you. We break down the transition from old-school imperative loops—where you micromanage every step—to modern declarative programming that focuses simply on what you want to do.
In this video, you will learn:
• Imperative vs. Declarative: Why modern loops are cleaner and less prone to errors.
• The Consumer Interface: Understanding the "robotic arm" on the conveyor belt that powers the forEach method.
• The Evolution of Code: Watch us build a Consumer using an Anonymous Inner Class and then refactor it live.
• Lambda Expressions: How to strip away the boilerplate code (like method declarations and curly braces) to reach the cleanest final form.
Whether you are preparing for a Java interview or just want to write code that is easier to read and manage, mastering these concepts is a core skill.
Key Concepts: Java 8, Functional Interfaces, Consumer Interface, Lambda Expressions, Clean Code.
