Answer 1

In Java 8, you can write this in two simple lines! In addition you can take advantage of parallel computing.

Here's the most beautiful way to do this:

Stream stream = Stream.of(text.toLowerCase().split("\\W+")).parallel();

Map wordFreq = stream
     .collect(Collectors.groupingBy(String::toString,Collectors.counting()));
