Description

The list of methods to do Byte Array to Hex are organized into topic(s).

Method

voidbytetoHex(final byte data, final StringBuffer buffer)
Transforms a byte to a hexadecimal string. 
int high = ((data & 0xf0) >> 4);
int low = (data & 0x0f);
buffer.append(HEX_CHARACTER[high]);
buffer.append(HEX_CHARACTER[low]);
StringbyteToHex(int val)
Very fast 8-bit int to hex conversion, with zero-padded output. 
return HEX_CONSTANTS[val & 0xff];
StringBufferbyteToHex(int val, StringBuffer sb)
byte To Hex 
sb.append(HEX_DIGITS[(val >> 4) & 0xf]);
sb.append(HEX_DIGITS[val & 0xf]);
return sb;
StringbyteToHexDisplayString(byte[] b)
Converts byte array to a string representation of hex bytes for display purposes. 
if (null == b)
    return "(null)";
int hexVal;
StringBuilder sb = new StringBuilder(b.length * 2 + 2);
sb.append("0x");
for (byte aB : b) {
    hexVal = aB & 0xFF;
    sb.append(hexChars[(hexVal & 0xF0) >> 4]);

intbyteToHexWord(byte in)
byte To Hex Word 
byte[] table = { 0x30, 0x31, 0x32, 0x33, 0x34, 0x35, 0x36, 0x37, 0x38, 0x39, 0x41, 0x42, 0x43, 0x44, 0x45,
        0x46 };
int result = 0x0000;
result = (table[(in & 0xF0) >>> 4]) << 8;
result = (result & 0xFF00) | (table[in & 0x0F]);
return result;
StringbyteToLowerHex(final byte b)
Retrieves a string representation of the provided byte in hexadecimal. 
return BYTE_HEX_STRINGS[LOWER_CASE][b & 0xFF];
StringbyteToTwoHexString(final byte data)
Convert a byte to a String of two Hex characters, with leading zero. 
final StringBuffer buffer;
final String strHex;
buffer = new StringBuffer();
strHex = Integer.toHexString(data & 0xFF);
if (strHex.length() == 0) {
    buffer.append("00");
} else if (strHex.length() == 1) {
    buffer.append("0");
