Convert byte array to Hex string

BytesToHexString.java

javax.xml.bind.DatatypeConverter.printHexBinary(bytes);

BytesToHexStringFunction.java

String convertToHex(byte[] data) {
	StringBuffer buf = new StringBuffer();
	for (int i = 0; i < data.length; i++) {
		int halfbyte = (data[i] >>> 4) & 0x0F;
		int two_halfs = 0;
		do {
			if ((0 <= halfbyte) && (halfbyte <= 9))
				buf.append((char) ('0' + halfbyte));
			else
				buf.append((char) ('A' + (halfbyte - 10)));
			halfbyte = data[i] & 0x0F;
		} while (two_halfs++ < 1);
	}
	return buf.toString();
}

Thanks . It is working !
