Java 8 Programmer II Study Guide: Exam 1Z0-809

Overview

This is the e-book version of my online Java 8 Programmer II Study Guide.

The exam for the  Oracle Certified Professional, Java SE 8 Programmer certification is hard. New APIs, lambdas, and streams, it covers a lot. But this book can help you.

This book has complete coverage of the Java 8 SE Programmer II (1Z0-809) exam objectives. Each chapter presents the content in a simple and conversational style to facilitate the comprehension of the topics. You'll also find key points and sample questions at the end of each chapter to reinforce key concepts and prepare you for the real exam.

Most study guides follow the topic structure of the certification exam. This book doesn't. The chapters are organized in a way I feel it's more natural to present the topics:
