        /*
         * The program steps through the string referred to
         * by searchMe one character at a time. For each
         * character, the program calls the regionMatches
         * method to determine whether the substring
         * beginning with the current character matches the
         * string the program is looking for.
         */
        for (int i = 0; i <= (searchMeLength - findMeLength); i++)
        {
            if (searchMe.regionMatches(i, findMe, 0, findMeLength))
            {
                foundIt = true;
                System.out.println("foundIt = " + foundIt);
                System.out.println(searchMe.substring(i, i
                        + findMeLength));

            }
        }
        if (!foundIt)

    }
}
