Method

byte[]intToBytes(int i)
int To Bytes 
byte[] bytes = new byte[4];
bytes[3] = (byte) (i & MASK_TO_BYTE);
i >>= NUMBER_OF_BITS_IN_A_BYTE;
bytes[2] = (byte) (i & MASK_TO_BYTE);
i >>= NUMBER_OF_BITS_IN_A_BYTE;
bytes[1] = (byte) (i & MASK_TO_BYTE);
i >>= NUMBER_OF_BITS_IN_A_BYTE;
bytes[0] = (byte) (i & MASK_TO_BYTE);
...
byte[]intToBytes(int i)
int To Bytes 
boolean neg = false;
int digs = 1;
if (i < 0) {
    digs++;
    neg = true;
    i = -i;
int base10 = 10;
...
byte[]intToBytes(int i)
Spilts an int into 4 bytes 
return new byte[] { (byte) (i >> 24), (byte) (i >> 16), (byte) (i >> 8), (byte) i };
byte[]intToBytes(int i)
Converts primitive int type to byte array. 
return toBytes(i, new byte[4], 0, 4);
byte[]intToBytes(int i)
int To Bytes 
byte[] intBytes = new byte[4];
intBytes[0] = (byte) (i >> 24);
intBytes[1] = (byte) (i >> 16);
intBytes[2] = (byte) (i >> 8);
intBytes[3] = (byte) (i >> 0);
return intBytes;
byte[]intToBytes(int i)
This function converts a integer to its corresponding byte array format. 
byte[] buffer = new byte[4];
intToBytes(i, buffer, 0);
return buffer;
byte[]IntToBytes(int i)
Int To Bytes 
byte abyte0[] = new byte[2];
abyte0[1] = (byte) (0xff & i);
abyte0[0] = (byte) ((0xff00 & i) >> 8);
return abyte0;
voidintToBytes(int i, byte[] data, int[] offset)
Write the bytes representing i into the byte array data, starting at index offset [0], and increment offset [0] by the number of bytes written; if data == null, increment offset [0] by the number of bytes that would have been written otherwise. 
if (data != null) {
    for (int j = (offset[0] + SIZE_INT) - 1; j >= offset[0]; --j) {
        data[j] = (byte) i;
        i >>= 8;
offset[0] += SIZE_INT;
byte[]intToBytes(int i_)
Converts an int into a byte array. 
byte abInt[] = new byte[4];
abInt[3] = (byte) (i_ & 255);
abInt[2] = (byte) ((i_ >> 8) & 255);
abInt[1] = (byte) ((i_ >> 16) & 255);
abInt[0] = (byte) (i_ >> 24);
return abInt;
byte[]intToBytes(int intValue)
int To Bytes 
byte[] b = new byte[4];
for (int i = 0; i < 4; i++) {
    b[i] = (byte) (intValue >> 8 * (3 - i) & 0xFF);
return b;
