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

This is the Kindle 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.
