         * Examples:
         * <blockquote><pre>
         * "hamburger".substring(4?? 8) returns "urge"
         * "smiles".substring(1?? 5) returns "mile"
         * </pre></blockquote>

         * @param      beginIndex   the beginning index?? inclusive.
         * @param      endIndex     the ending index?? exclusive.
         * @return     the specified substring.
         * @exception  IndexOutOfBoundsException  if the
         *             <code>beginIndex</code> is negative?? or
         *             <code>endIndex</code> is larger than the length of
         *             this <code>String</code> object?? or
         *             <code>beginIndex</code> is larger than
