Java - Filtering List Entries by Regex

Question

My code looks like this:

List filterList(List list, String regex) {
  List result = new ArrayList();
         


        

Answer 1

In addition to the answer from Konstantin: Java 8 added Predicate support to the Pattern class via asPredicate, which calls Matcher.find() internally:

Pattern pattern = Pattern.compile("...");

List matching = list.stream()
                            .filter(pattern.asPredicate())
                            .collect(Collectors.toList());

Pretty awesome!
