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

Method

byte[]intToByteArray(int i)
converts an int to an array of bytes. 
byte[] ret = new byte[4];
ret[0] = (byte) ((i & 0xff000000) >> 24);
ret[1] = (byte) ((i & 0x00ff0000) >> 16);
ret[2] = (byte) ((i & 0x0000ff00) >> 8);
ret[3] = (byte) (i & 0x000000ff);
return ret;
byte[]intToByteArray(int input)
Utility method for converting a int into a byte[] 
byte[] output = new byte[4];
intToByteArray(input, output, 0);
return output;
byte[]intToByteArray(int integer)
int To Byte Array 
return new byte[] { (byte) ((integer & 0xFF000000) >> 24), (byte) ((integer & 0x00FF0000) >> 16),
        (byte) ((integer & 0x0000FF00) >> 8), (byte) ((integer & 0x000000FF)) };
byte[]intToByteArray(int integer)
Converts an integer into an unsigned 4-byte array. 
byte[] intBytes = new byte[4];
intBytes[0] = (byte) ((integer & 0xff000000) >>> 24);
intBytes[1] = (byte) ((integer & 0x00ff0000) >>> 16);
intBytes[2] = (byte) ((integer & 0x0000ff00) >>> 8);
intBytes[3] = (byte) ((integer & 0x000000ff));
return intBytes;
byte[]intToByteArray(int piValueToConvert, boolean pbBigEndian)
Converts an int value to a byte array. 
byte[] aRetVal = new byte[4];
byte iLowest;
byte iLow;
byte iMid;
byte iHigh;
iLowest = (byte) (piValueToConvert & 0xFF);
iLow = (byte) ((piValueToConvert >> 8) & 0xFF);
iMid = (byte) ((piValueToConvert >> 16) & 0xFF);
...
voidintToByteArray(int pSrc, byte[] pDst, int pOffset)
int To Byte Array 
pDst[pOffset] = (byte) (pSrc >>> 24);
pDst[pOffset + 1] = (byte) (pSrc >>> 16);
pDst[pOffset + 2] = (byte) (pSrc >>> 8);
pDst[pOffset + 3] = (byte) pSrc;
byte[]intToByteArray(int source)
Converts the bypassed int value to a byte array. 
byte[] result = new byte[4];
for (int i = 0; i < 4; ++i) {
    result[3 - i] = (byte) ((source & (0xff << (i << 3))) >>> (i << 3));
return result;
voidIntToByteArray(int val, byte[] buf, int offset)
Write integer into buf[offset]...buf[offset+3] 
buf[0 + offset] = (byte) ((val >> 24) & 255);
buf[1 + offset] = (byte) ((val >> 16) & 255);
buf[2 + offset] = (byte) ((val >> 8) & 255);
buf[3 + offset] = (byte) (val & 255);
byte[]intToByteArray(int value)
int To Byte Array 
return new byte[] { (byte) (value >>> 24), (byte) (value >>> 16), (byte) (value >>> 8), (byte) value };
byte[]intToByteArray(int value)
int To Byte Array 
try {
    return new byte[] { (byte) (value >>> 24), (byte) (value >>> 16), (byte) (value >>> 8),
            (byte) (value) };
} catch (NullPointerException npe) {
    return null;
