Method

byte[]intToByte(int number)
int To Byte 
byte[] b = new byte[4];
for (int i = 3; i >= 0; i--) {
    b[i] = (byte) (number % 256);
    number >>= 8;
return b;
byte[]intToByte(int number, int byteLength)
int To Byte 
byte[] bLocalArr = new byte[byteLength];
for (int i = 0; (i < 4) && (i < byteLength); i++) {
    bLocalArr[i] = (byte) (number >> 8 * i & 0xFF);
return bLocalArr;
intintToByte(int v, byte[] dest)
int To Byte 
int destOffset = 0;
dest[destOffset++] = (byte) ((v >> 24) & 0xFF);
dest[destOffset++] = (byte) ((v >> 16) & 0xFF);
dest[destOffset++] = (byte) ((v >> 8) & 0xFF);
dest[destOffset++] = (byte) (v & 0xFF);
return destOffset;
byteintToByte(int value)
Convert integer to a single byte. 
byte[] bytes = intToBytes(value, 4);
return bytes[3];
byteintToByte(int value)
This function converts integer to one byte 
if ((value > Math.pow(2, 15)) || (value < 0)) {
    throw new Exception("Integer value " + value + " is larger than 2^15");
return (byte) (value & 0xFF);
byte[]intToByte(int[] values)
int To Byte 
if (values == null) {
    return null;
byte[] results = new byte[values.length];
for (int i = 0; i < values.length; i++) {
    results[i] = (byte) values[i];
return results;
...
byte[]intToByte4(int number)
Method converting int into byte array. 
int tmp_num = number;
byte[] byte4 = new byte[4];
for (int i = byte4.length - 1; i > -1; i--) {
    byte4[i] = (byte) (tmp_num & 0xff);
    tmp_num = tmp_num >> 8;
return byte4;
byte[]intToByteArr(int v)
int To Byte Arr 
return new byte[] { (byte) (v >>> 24), (byte) (v >>> 16), (byte) (v >>> 8), (byte) (v) };
