Java Programming for Complete Beginners - Java 16 - Step 13 - Behind the Screens with Functional Interfaces - Implement

The video tutorial explores Lambda expressions in Java, focusing on their functionality behind the scenes. It explains how Lambda expressions work with functional interfaces, particularly the Predicate interface, and demonstrates filtering even numbers from a list using streams. The tutorial includes a practical example of implementing a custom Predicate interface to understand how Java handles Lambda expressions and functional interfaces.

What is the purpose of a functional interface in Java?

Explain how the filter method works in the context of streams.

What is a predicate in Java, and how is it used?

What is the significance of the test method in the predicate interface?

Describe the process of creating an implementation of a functional interface.

How does the Java compiler handle lambda expressions?

What exercise is suggested for understanding the forEach interface?
