Hey Harry I was preparing from "OCP Oracle Certified Professional Java SE 11 Developer Complete Study Guide: Exam 1Z0-815, Exam 1Z0-816, and Exam 1Z0-817 " this book. But is this book "Ocp Oracle Certified Professional Java Se 17 Study Guide: Exam 1z0-829" a newer version of the previous one. Or is it a different certification book ?
Im preparing for 1Z0-815, 1Z0-816, 1Z0-817, 1Z0-819 exam. So is the Exam 1z0-829 book a newer version of the previous one or should I just stay with the current one ?

Hi Ramanna, the 1z0-829 is Java 17 exam certification. That book will prepare you for version 17 of java instead of version 11. Even though version 17 of java is different(more higher) majority of the content will remain same (just a general information for you). If you are interested in Java 11 you should follow the first book you mentioned. Please let me know if that answers your question.

[@ramannaagre7938]

@@harrygill6169 Alright, very clear now. Just one question, besides the updates in the version 17, does this book contain all of the content from the Java SE 11 book, because the version 17 book is a lot cheaper than the version 11 book, so that I can buy the version 17 one.

[@harrygill6169]

Not a problem. Apart from some new additions I believe it will be exactly same. What I would recommend is give Java 17 certification directly but if you are keen to give java 11 certification you can use the Java 17 book. Pretty confident that book will mention the new features that are added in version 17 so just be aware. Majority of the concepts should be same. Here is the link if you are interested differences between Java 11 and 17.

This is a good video @harrygill6169. I have watched the Stream videos and they are really to the point and states the concept clearly. I have one request to you, could you please do a video on the java module?

[@harrygill6169]

Thanks a lot Kunal for your comment and feedback. And sorry for very late reply I have not been working on videos for quite some time due to job change. And noted I can work on Java Modules next. Thanks.
