Usage

From source file:is.java

  public static void main(String[] args) {
  List<Integer> list = Arrays.asList(3, 2, 4, 1, 5);
  NavigableSet<Integer> ns = new TreeSet<Integer>(list);
  System.out.println("Ascending order (default): " + ns);

  Iterator<Integer> descendingIterator = ns.descendingIterator();
  StringBuilder sb = new StringBuilder("Descending order: ");
  while (descendingIterator.hasNext()) {
    int m = descendingIterator.next();
    sb.append(m + " ");
  }/*from   w  w w  .  j  ava  2s.  c om*/
  System.out.println(sb);

  int greatest = ns.lower(3);
  System.out.println("Lower of 3 = " + greatest);

  int smallest = ns.higher(3);
  System.out.println("Higher of 3 = " + smallest);
