Method

StringtoGuidString(UUID uuid)
to Guid String 
byte[] guidBytes = toGuidBytes(uuid);
String to = toHex(guidBytes);
return to;
StringtoHex(byte[] bytes)
Returns hex-digit (lower case) string. 
StringBuffer buf = new StringBuffer(bytes.length * 2);
for (int i = 0; i < bytes.length; i++) {
    int value = (int) bytes[i] & 0xff;
    if (value < 0x10) {
        buf.append("0");
    buf.append(Integer.toHexString(value));
return buf.toString();
StringtoHexBytes(byte[] bytes)
Converts the given bytes into a hexadecimal representation. 
return toHexBytes(bytes, 0, bytes.length);
StringtoHexString(Number n)
to Hex String 
if (n == null)
    return "null";
byte[] bytes = new byte[8];
ByteBuffer bytesBuffer = ByteBuffer.wrap(bytes);
LongBuffer longBuffer = bytesBuffer.asLongBuffer();
longBuffer.put(0, n.longValue());
StringBuilder sb = new StringBuilder(16);
for (int i = 0; i < bytes.length; i++) {
...
int[]toInt(byte[] bytes)
to Int 
ByteBuffer byteBuffer = ByteBuffer.wrap(bytes);
IntBuffer buffer = byteBuffer.asIntBuffer();
int ret[] = new int[buffer.capacity()];
buffer.get(ret);
return ret;
inttoInt(byte[] data)
to Int 
return ByteBuffer.wrap(data).getInt();
inttoInt(byte[] value)
Convert the first 4 bytes of an array to a big endian int. 
if (value == null) {
    return 0;
int val = 0;
if (value.length >= 1) {
    val |= ((value[0] & 0xFF) << 24);
if (value.length >= 2) {
...
inttoInt(final byte lowOrderByte, final byte highOrderByte)
to Int 
return toInt(lowOrderByte, highOrderByte, ByteOrder.LITTLE_ENDIAN);
inttoInt(InetAddress address)
Converts ipv4 InetAddress to Integer. 
return ByteBuffer.wrap(address.getAddress()).getInt();
int[]toIntArray(byte[] byteArray)
Returns a new integer array using data from the given byte array. 
IntBuffer intBuffer = ByteBuffer.wrap(byteArray).asIntBuffer();
int[] intArray = new int[intBuffer.limit()];
intBuffer.get(intArray);
return intArray;
