Method

String bufferToHex(byte bytes[])
buffer To Hex

return bufferToHex(bytes, 0, bytes.length);

String bufferToHexString(byte[] buffer)
Convert a byte buffer to a hexadecimal string.

StringBuffer sb = new StringBuffer(buffer.length * 2);
for (int i = 0; i < buffer.length; i++) {
 char a = HEX_CHARS[(buffer[i] & 0xF0) >> 4];
 char b = HEX_CHARS[buffer[i] & 0x0F];
 sb.append(a);
 sb.append(b);
return sb.toString();
...

String bufferToHexString(byte[] data, int start, int length)
buffer To Hex String

int i;
int myStop;
StringBuilder sb = new StringBuilder();
myStop = (length > data.length) ? data.length : length;
for (i = start; i < start + myStop; i++) {
 sb.append(String.format("%02x ", data[i]));
return sb.toString();
...

String bytes2Hex(byte bt)
bytes Hex

return ("" + "0123456789ABCDEF".charAt(0xf & bt >> 4) + "0123456789ABCDEF".charAt(bt & 0xf));

String bytes2Hex(byte... values)
bytes Hex

StringBuffer bf = new StringBuffer();
for (byte b : values) {
 String str = byte2Hex(b, false);
 bf.append(str);
return bf.toString();

String bytes2Hex(byte[] abValue)
bytes Hex

if (abValue == null) {
 return null;
String sTemp;
StringBuffer sbHex = new StringBuffer();
for (int i = 0; i < abValue.length; i++) {
 sTemp = Integer.toHexString(abValue[i] & 0XFF);
 if (1 == sTemp.length()) {
...

String bytes2Hex(byte[] b)
bytes Hex

StringBuilder sb = new StringBuilder(1024);
for (int n = 0; n < b.length; n++) {

 char lower = Character.forDigit(_b % 16, 16);
 str.append(upper);
 str.append(lower);
return str.toString();

String bytes2Hex(byte[] bts)
bytes Hex

String des = "";
String tmp = null;
for (int i = 0; i < bts.length; i++) {
 tmp = Integer.toHexString(bts[i] & 0xFF);
