Usage

From source file:Main.java

public static void main(String[] args) {

    ns.add(3);
    ns.add(4);
    ns.add(5);
    ns.add(6);

    // Get a reverse view of the navigable set
    NavigableSet<Integer> reverseNs = ns.descendingSet();

    // Print the normal and reverse views
    System.out.println("Normal order: " + ns);
    System.out.println("Reverse order: " + reverseNs);

    NavigableSet<Integer> threeOrMore = ns.tailSet(3, true);
    System.out.println("3 or  more:  " + threeOrMore);
    System.out.println("lower(3): " + ns.lower(3));
