Usage

From source file:Main.java

public static void main(String[] args) {

    TreeSet<Integer> treeadd = new TreeSet<Integer>();

    treeadd.add(1);/*w  w w.j  ava  2 s  . com*/
    treeadd.add(3);
    treeadd.add(17);
    treeadd.add(2);
    treeadd.add(20);

    // displaying the greatest element < 17
    System.out.println("Greatest element less than 17 is: " + treeadd.lower(17));
