I purchased the certification book for
Java 6, by authors Kathy Sierra and Bert Bates. They also provided a disc at the time where I could read on my computer. I recently purchased "OCP Java SE11 Programmer II Study Guide". Is a electronic version of "OCP Java SE11 Programmer II Study Guide" provided when you purchase the hard copy? The authors for this book is Scott Selikoff and Jeanne Boyarsky.
