Method

StringbytesToHexString(byte[] b)
Convert a vector of bytes into a regularily formatted string of hexadecimal values. 
String space = " ";
StringBuilder sb = new StringBuilder();
for (int index = 0; index < b.length; index++) {
    int tmp = b[index];
    tmp &= 0xFF;
    sb.append("0x");
    if (tmp < 16)
        sb.append(space);
...
StringbytesToHexString(byte[] b, int length)
Converts byte array to a string representation of hex bytes. 
StringBuilder sb = new StringBuilder(length * 2);
for (int i = 0; i < length; i++) {
    int hexVal = b[i] & 0xFF;
    sb.append(hexChars[(hexVal & 0xF0) >> 4]);
    sb.append(hexChars[(hexVal & 0x0F)]);
return sb.toString();
StringbytesToHexString(byte[] bArray)
bytes To Hex String 
StringBuffer sb = new StringBuffer(bArray.length);
String sTemp;
for (int i = 0; i < bArray.length; i++) {
    sTemp = Integer.toHexString(0xFF & bArray[i]);
    if (sTemp.length() < 2)
        sb.append(0);
    sb.append(sTemp);
return sb.toString();
StringbytesToHexString(byte[] bArray)
bytes To Hex String 
StringBuffer sb = new StringBuffer(bArray.length);
for (int i = 0; i < bArray.length; i++) {
    String sTemp = byteToHexString(bArray[i]);
    sb.append(sTemp.toUpperCase());
return sb.toString();
StringbytesToHexString(byte[] bs)
bytes To Hex String 
if (bs == null || bs.length == 0) {
    return "";
StringBuffer str = new StringBuffer(bs.length * 4);
for (int i = 0; i < bs.length; i++) {
    str.append(hex[(bs[i] >> 4) & 0x0f]);
    str.append(hex[bs[i] & 0x0f]);
return str.toString();
StringbytesToHexString(byte[] buf)
bytes To Hex String 
final String decimals = "0123456789ABCDEF";
if (buf == null)
    return null;
char[] r = new char[buf.length * 2];
for (int i = 0; i < buf.length; ++i) {
    r[i * 2] = decimals.charAt((buf[i] & 0xf0) >> 4);
    r[i * 2 + 1] = decimals.charAt(buf[i] & 0x0f);
return new String(r);
StringbytesToHexString(byte[] byteArray)
bytes To Hex String 
StringBuilder sb = new StringBuilder();
for (byte b : byteArray) {
    sb.append(String.format("%02X ", b));
return sb.toString();
StringbytesToHexString(byte[] bytes)
Creates a string of hexadecimal representation of bytes from an array of bytes, separated by white spaces 
if (bytes.length == 0) {
    return "";
char[] resultString = new char[bytes.length * 3];
int byteValue;
for (int i = 0; i < bytes.length; i++) {
    byteValue = bytes[i] & ONE_BYTE_MASK;
    resultString[i * 3] = hexChars[byteValue >>> 4]; 
...
StringbytesToHexString(byte[] bytes)
bytes To Hex String 
if (bytes == null) {
    return "null";
String ret = "";
StringBuffer buf = new StringBuffer();
for (int i = 0; i < bytes.length; i++) {
    if (i > 0) {
        ret += ":";
...
StringbytesToHexString(byte[] bytes)
bytes To Hex String 
char[] buf = new char[bytes.length * 2];
int radix = 1 << 4;
int mask = radix - 1;
for (int i = 0; i < bytes.length; i++) {
    buf[2 * i] = hexDigit[(bytes[i] >>> 4) & mask];
    buf[2 * i + 1] = hexDigit[bytes[i] & mask];
return new String(buf);
