Method

StringbytesToHex(byte[] bytes)
bytes To Hex 
return bytesToHex(bytes, bytes.length);
StringbytesToHex(byte[] bytes)
bytes To Hex 
char[] hexChars = new char[bytes.length * 2];
for (int j = 0; j < bytes.length; j++) {
    int v = bytes[j] & 0xFF;
    hexChars[j * 2] = hexArray[v >>> 4];
    hexChars[j * 2 + 1] = hexArray[v & 0x0F];
return new String(hexChars);
StringbytesToHex(byte[] bytes)
Helper method to convert a byte array to a hexadecimal string. 
StringBuilder sb = new StringBuilder();
for (byte hashByte : bytes) {
    int intVal = 0xff & hashByte;
    if (intVal < 0x10) {
        sb.append('0');
    sb.append(Integer.toHexString(intVal));
return sb.toString();
StringbytesToHex(byte[] bytes)
translate a byte array of raw data into a String with a hex representation of that data 
return bytesToHex(bytes, null);
StringbytesToHex(byte[] bytes)
Transforms byte to hex representation 
StringBuilder buffer = new StringBuilder(2 * bytes.length);
for (int i = 0; i < bytes.length; ++i) {
    buffer.append(Character.forDigit((bytes[i] >> 4) & 0xF, 16));
    buffer.append(Character.forDigit(bytes[i] & 0xF, 16));
return buffer.toString();
StringbytesToHex(byte[] bytes)
bytes To Hex 
return bytesToHex(bytes, false);
StringbytesToHex(byte[] bytes)
bytes To Hex 
StringBuilder sb = new StringBuilder();
int t;
for (int i = 0; i < 16; i++) {
    t = bytes[i];
    if (t < 0) {
        t += 256;
    sb.append(hexDigits[(t >>> 4)]);

StringbytesToHex(byte[] bytes)
bytes To Hex 
StringBuilder sb = new StringBuilder();
for (byte b : bytes) {
    sb.append(String.format("%02X ", b));
return sb.toString();
StringbytesToHex(byte[] bytes)
bytes To Hex 
char[] hexChars = new char[bytes.length * 2];
int v;
for (int j = 0; j < bytes.length; j++) {
    v = bytes[j] & 0xFF;
    hexChars[j * 2] = hexArray[v >>> 4];

StringbytesToHex(byte[] bytes)
bytes To Hex 
char[] str = new char[bytes.length << 1];
for (int i = 0, j = 0; i < bytes.length; i++) {
    str[j++] = HEX[(bytes[i] & 0xf0) >>> 4];
    str[j++] = HEX[bytes[i] & 0x0f];
return new String(str);
