Method

StringbyteArrayToHexString(byte[] bytes)
byte Array To Hex String 
int oldLength = bytes.length;
byte[] positiveBytes = new byte[oldLength + 1];
System.arraycopy(bytes, 0, positiveBytes, 1, oldLength);
positiveBytes[0] = 1;
BigInteger bigInt = new BigInteger(positiveBytes);
String hex = bigInt.toString(16);
return hex.substring(1);
StringbytesToHex(byte[] data)
Convenience method to convert a byte array to a hex string. 
StringBuffer buf = new StringBuffer();
for (int i = 0; i < data.length; i++) {
    buf.append(byteToHex(data[i]).toUpperCase());
return (buf.toString());
StringconvertToHex(byte[] in)
convert To Hex 
StringBuilder builder = new StringBuilder(in.length * 2);
Formatter formatter = new Formatter(builder);
for (byte inByte : in)
    formatter.format("%02x", inByte);
formatter.close();
return formatter.toString();
StringconvertToHex(byte[] raw)
convert To Hex 
final StringBuilder hex = new StringBuilder(raw.length * 2);
for (final byte b : raw) {
    hex.append(HEX_DIGITS.charAt((b & 0xF0) >> 4)).append(
            HEX_DIGITS.charAt((b & 0x0F)));
return hex.toString();
Stringbytes2Hex(byte[] bts)
bytes Hex 
String des = "";
String tmp = null;
for (int i = 0; i < bts.length; i++) {
    tmp = (Integer.toHexString(bts[i] & 0xFF));
    if (tmp.length() == 1) {
        des += "0";
    des += tmp;
...
Stringbytes2HexString(byte[] bytes)
bytes Hex String 
if (bytes == null)
    return null;
StringBuilder ret = new StringBuilder(2 * bytes.length);
for (int i = 0; i < bytes.length; i++) {
    int b;
    b = 0x0f & (bytes[i] >> 4);
    ret.append("0123456789ABCDEF".charAt(b));
    b = 0x0f & bytes[i];
...
Stringbytes2hex(byte[] bytes)
byteshex 
StringBuffer strbuf = new StringBuffer(bytes.length * 2);
for (int i = 0; i < bytes.length; i++) {
    int bt = bytes[i] & 0xff;
    if (bt < 0x10) {
        strbuf.append("0");
    strbuf.append(Integer.toHexString(bt));
return strbuf.toString();
StringbytesToHex(byte[] bytes)
Convert Byte array to Hex (string) 
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[] data)
Convenience method to convert a byte array to a hex string. 
StringBuilder buf = new StringBuilder();
for (int i = 0; i < data.length; i++) {
    buf.append(byteToHex(data[i]).toUpperCase());
return (buf.toString());
StringbytesToHex(byte[] data)
bytes To Hex 
return bytesToHex(data, 0, data.length);
