One liner for getting a sublist from a Set
- by yegor256
Is there a one-liner (maybe from Guava or Apache Collections) that gets a sublist from a set. Internally it should do something like this:
public <T> List<T> sublist(Set<T> set, int count) {
Iterator<T> iterator = set.iterator();
List<T> sublist = new LinkedList<T>();
int pos = 0;
while (iterator.hasNext() && pos++ < count) {
sublist.add(iterator.next());
}
return sublist;
}
Obviously, if there are not enough elements it has to return as many as possible.
