Answer 1

/*
     * Returns true if string contains atlesat one alphabet(lowercase or uppercase).
     */
    public static boolean containsAtLeastOneAlphabet(String str)
    {
        int x;
        for(int j = 0 ; j < str.length() ; j++)
        {
            x = (int)str.charAt(j);
            if((x >= 65 && x <= 90) || (x >= 97 && x <= 122))
                return true;
        }
        return false;
    }
