Does it have any performance tuning parameters in terms of garbage collection?

Hello Nilesh,
The book does not cover anything related to garbage collection. Jdk 9 made two changes to garbage collection:

1. Made Garbage-First(G1) the default garbage collector
2. Deprecated the Concurrent Mark Sweep (CMS) Garbage Collector

You can find little more about them at:
1. http://openjdk.java.net/jeps/248
2. http://openjdk.java.net/jeps/291

IMHO, none of these changes were significant enough for an application developer's perspective to warrant a section or chapter in the book.

Thanks
Kishori
