StringprintHex(byte[] array)
print Hex 
return printHex(array, 0, array.length);
StringprintHex(byte[] array, int offset, int len)
Get a hexadecimal representation of a byte array starting at offset index for len bytes, with each octet separated by a space. 
StringBuilder sb = new StringBuilder();
for (int i = 0; i < len; i++) {
    byte b = array[offset + i];
    if (sb.length() > 0)
        sb.append(' ');
    sb.append(digits[b >> 4 & 0x0F]);
    sb.append(digits[b & 0x0F]);
return sb.toString();
StringprintHex(byte[] b)
print Hex 
StringBuffer res = new StringBuffer();
StringBuffer t, t1;
for (int i = 0; i < b.length; i++) {
    t = new StringBuffer(Integer.toHexString(b[i]));
    if (t.length() > 2) {
        t1 = new StringBuffer();
        t1.append(t.charAt(t.length() - 2));
        t1.append(t.charAt(t.length() - 1));
...
voidprintHex(byte[] bytes)
