Create a list from an existing Set

Using a new List

List<String> list = new ArrayList<String>(listOfElements);

Using List.addAll() method

Set<String> set = new HashSet<String>();
set.add("foo");
set.add("boo");

List<String> list = new ArrayList<String>();
list.addAll(set);

Using Java 8 Steam API

List<String> list = set.stream().collect(Collectors.toList());
