An example of good idiomatic Java 8 source code.

Example:

If only enterprise didn't move so slow =/. I wish I could migrate to 8.

Thanks. Curious... are the parens meaningful in this method body?

    private int getPartition(int globalInsertionPosition) {
        return (globalInsertionPosition) / this.sizePerPartition;
    }

No, that's likely a leftover from refactoring. Good spot.

Haha, no worries! I've been checked out of Java for a while and I was a little bit worried that this was semantically meaningful, which would be a pretty confusing addition to the language :)

What are the Java 8 features being used here, besides the obvious lambda expressions?

(genuine question, I haven't stayed current with Java)

Streams are also being used.

Optional is also new to Java 8 although syntactically very similar that Guava.
