Returns the index of the nearest bit that is set to true that occurs on or before the specified starting index. If no such bit exists, or if -1 is given as the starting index, then -1 is returned. To iterate over the true bits in a BitSet, use the followin

(int fromIndex)

     *                                   than {@code -1}
