import java.util.TreeSet;

/*
 * Example of floor(E e) method.
 */
public class TreeSetExample
{
    public static void main( String[] args )
    {

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

        treeSet.add(40);
        treeSet.add(20);
        treeSet.add(30);
        treeSet.add(10);
        treeSet.add(50);

        System.out.println("treeSet : " + treeSet + "\n");

        /*
         * Returns the greatest element in this set less than or equal to the
         * given element, or null if there is no such element.
         */
        
        Integer value = treeSet.floor(22);
        System.out.println("floor(22) : " + value);

        value = treeSet.floor(37);
        System.out.println("\nfloor(37) : " + value);

        value = treeSet.floor(40);
        System.out.println("\nfloor(40) : " + value);

        value = treeSet.floor(5);
        System.out.println("\nfloor(5) : " + value);

    }
}

Output

treeSet : [10, 20, 30, 40, 50]

floor(22) : 20

floor(37) : 30

floor(40) : 40

floor(5) : null
