 * Example of tailSet(E fromElement,boolean inclusive) method.

    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 a view of the portion of this set whose elements are greater
         * than (or equal to, if inclusive is true) fromElement.
         * 
         * The returned set is backed by this set, so changes in the returned
         * set are reflected in this set, and vice-versa. The returned set
         * supports all optional set operations that this set supports.
         */

        NavigableSet<Integer> navigableSet = treeSet.tailSet(20, false);
        System.out.println("inclusive is false , navigableSet : "
                + navigableSet + "\n");

        navigableSet = treeSet.tailSet(20, true);
        System.out.println("inclusive is true , navigableSet : " + navigableSet
                + "\n");

    }
}

Output

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

inclusive is false , navigableSet : [30, 40, 50]

inclusive is true , navigableSet : [20, 30, 40, 50]
