Part 1. Fundamentals

This first part of the book provides the fundamentals to help you get started with the new Java ideas introduced in Java 8. By the end of this first part, you’ll have a full understanding of what lambda expressions are, and you’ll be able to write code that’s both concise and flexible enough to easily adapt to changing requirements.

In chapter 1, we summarize the main changes to Java (lambda expressions, method references, streams, and default methods) and set the scene for the book.

In chapter 2, you’ll learn about behavior parameterization, a software development pattern that Java 8 relies heavily on and is the motivation for lambda expressions.

Chapter 3 gives a full explanation, with code examples and quizzes at every step, of the concepts of lambda expressions and method references.
