I assume you could/should read these 2 chapters:
Chapter 10: Programming with the Date and Time APIChapter 11: Understanding Lambda Expressions
But I would be surprised if the coverage in these chapters is enough to pass the upgrade to OCPJP8 exam as for this exam you'll need to know much more advanced topics than for the OCAJP8 exam.
