     * Get hexadecimal string representation of a byte.
     * Note: to get a hex string from a character, use <code>Integer.toHexString((int) c.charValue())</code>.
     * To get the ASCII value of a character, use <code>(int) c.charValue()</code>.
     * @param b Byte.
     * @return String with hex value.
    static public String toHex(final byte b) {
        final char hexDigit[] = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'};
        final char[] array = { hexDigit[(b >> 4) & 0x0f], hexDigit[b & 0x0f] };
        return new String(array);
     }//toHex()
     * Get hexadecimal string representation of a char.
     * @param c Char.
     * @return String with hex value.
    static public String toHex(final char c) {
        final byte hi = (byte) (c >>> 8);
        final byte lo = (byte) (c & 0xff);
        return toHex(hi) + toHex(lo);
    }//toHex()
