StringbytesToReadableHexStr(byte[] msg)
Convert a byte array to a formated hex string suitable for printing. 
return bytesToReadableHexStr(msg, 0, msg.length);
StringbytesToUpperCaseHex(byte[] b)
bytes To Upper Case Hex 
char hexDigit[] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F' };
StringBuffer buf = new StringBuffer();
for (int j = 0; j < b.length; j++) {
    buf.append(hexDigit[(b[j] >> 4) & 0x0f]);
    buf.append(hexDigit[b[j] & 0x0f]);
return buf.toString();
StringbyteToHex(byte a)
byte To Hex 
StringBuffer s = new StringBuffer();
s.append(Character.forDigit((a >> 4) & 0xf, 16));
s.append(Character.forDigit(a & 0xf, 16));
return s.toString();
StringbyteToHex(byte b)
byte To Hex 
int high = (b & 0xF0) >> 4;
int low = (b & 0x0F);
return "" + HEX.charAt(high) + HEX.charAt(low);
StringbyteToHex(byte b)
Converts a byte to the string representation of its hex value. 
char hexDigit[] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f' };
char[] array = { hexDigit[(b >> 4) & 0x0f], hexDigit[b & 0x0f] };
return new String(array);
StringbyteToHex(byte b)
byte To Hex 
return String.format("0x%02X", b);
StringbyteToHex(byte b)
Converts the given byte to a hex String. 
String hex = Integer.toHexString(b);
if (hex.length() >= 2) {
    return hex.substring(hex.length() - 2);
return String.format("0%s", hex);
StringbyteToHex(byte b)
Returns the hexadecimal representation of a byte. 
return String.format("%02X", b);
StringbyteToHex(byte b)
byte To Hex 
return hexNums[b >> 4 & 0x0f] + hexNums[b & 0x0f];
