Method

StringbytesToHex(byte[] b)
bytes To Hex 
StringBuilder sb = new StringBuilder();
for (int i = 0; i < b.length; i++) {
    sb.append(byteToHex(b[i])).append(" ");
return sb.toString();
StringbytesToHex(byte[] b, int offset, int length)
Converts a byte array to a hexadecimal string. 
StringBuffer sb;
String result;
int i, top;
top = offset + length;
if (length < 0 || top > b.length)
    throw new IllegalArgumentException();
sb = new StringBuffer();
for (i = offset; i < top; i++) {
...
StringbytesToHex(byte[] binary)
Convert binary array to a hex string. 
byte[] hex = new byte[binary.length * 2];
for (int i = 0; i < binary.length; i++) {
    hex[2 * i] = HexLookupTable[(binary[i] & 0xFF) >>> 4];
    hex[2 * i + 1] = HexLookupTable[binary[i] & 0xF];
return new String(hex);
StringbytesToHex(byte[] bs, int off, int length)
bytes To Hex 
StringBuffer sb = new StringBuffer(length * 2);
bytesToHexAppend(bs, off, length, sb);
return sb.toString();
StringbytesToHex(byte[] bt)
bytes To Hex 
StringBuilder stringBuilder = new StringBuilder();
if (bt == null || bt.length <= 0) {
    return null;
for (int i = 0; i < bt.length; i++) {
    int v = bt[i] & 0xFF;
    String hv = Integer.toHexString(v);
    if (hv.length() < 2) {
...
StringbytesToHex(byte[] buf)
bytes To Hex 
final StringBuilder b = new StringBuilder(buf.length * 2);
for (int i = 0; i < buf.length; i++) {
    final int cell = (int) (buf[i] & 0xFF);
    if (cell < 16) {
        b.append("0");
    b.append(Integer.toString(cell, 16));
return b.toString();
StringbytesToHex(byte[] bytes)
bytes To Hex 
return bytesToHex(bytes, 0, bytes.length);
StringbytesToHex(byte[] bytes)
Converts the provided byte array into a hexadecimal string with two characters per byte. 
return bytesToHex(bytes, false);
StringbytesToHex(byte[] bytes)
bytes To Hex 
StringBuffer hexString = new StringBuffer();
for (int i = 0; i < bytes.length; i++) {
    String hex = Integer.toHexString(bytes[i] & 0xFF);
    if (hex.length() < 2) {
        hexString.append(0);
    hexString.append(hex);
return hexString.toString();
StringbytesToHex(byte[] bytes)
bytes To Hex 
StringBuilder stringBuilder = new StringBuilder(bytes.length * 2);
for (int i = 0; i < bytes.length; i++) {
    String s = "0" + Integer.toHexString(bytes[i]);
    stringBuilder.append(s.substring(s.length() - 2, s.length()));
return stringBuilder.toString();
