Hello Mr. Subramaniam thank you for taking the time to answer questions here.
My question is: The examples of functional programming in
Java 8 that I've seen almost always deal with collections. I've also started using Scala and found that there is so much more to functional than map/reduce/foreach/etc. Does the book address Java 8 functional programming against other scenarios than taking a collection of data and obtaining a result from it somehow? For example, I understand higher-order functions are possible in Java 8. Is this addressed in the book?
