Some of us take for granted the newer features in Java, but, being a software consultant, I get to be involved in projects that are sometimes constrained to older versions of Java. The features from Java 1.8 that I have enjoyed for a few years are brand new to others.

I wrote this blog as a primer for those who are just getting started using java.util.Stream classes, or for those who haven’t had a chance to take a look at them until now. The quick topics below represent just a sampling of some of the ways to be more productive using java stream classes. Rather than providing a tutorial on how the classes are used, I’ll attempt to explain by example.
