Collect HashSet / Java 8 / Regex Pattern / Stream API

Question

Recently I change version of the JDK 8 instead 7 of my project and now I overwrite some code snippets using new features that came with Java 8.

final Matcher         


        

Answer 1

What about Pattern.splitAsStream ?

Stream stream = Pattern.compile(regex).splitAsStream(input);

and then a collector to get a set.

Set set = stream.map(String::toLowerCase).collect(Collectors.toSet());
