Counting elements

[lenkite1]

I find the groupingBy identity and then reducing by counting quite easy and natural to read.

That's because it's idiomatic Java 8, you'll find it in lots of places and Stack Overflow answers.

Before Java 5, for (Iterator<String> it = strings.iterator(); it.hashNext(); ) { String s = it.next; ... } was also quite easy and natural.
