     * "Harbison".substring(3) returns "bison"

     * "emptiness".substring(9) returns "" (an empty string)

     * </pre></blockquote>

     *

     * @param      beginIndex   the beginning index, inclusive.

     * @return     the specified substring.

     * @exception  IndexOutOfBoundsException  if

     *             <code>beginIndex</code> is negative or larger than the

     *             length of this <code>String</code> object.
