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

Method

voidint32ToArrayInPlace(int data, byte[] buffer, int offset)
Convert a 32 bit integer into a byte array, network order. 
buffer[offset] = (byte) (data >> 24);
buffer[offset + 1] = (byte) (data >> 16);
buffer[offset + 2] = (byte) (data >> 8);
buffer[offset + 3] = (byte) data;
voidint32ToByteArr(int val, byte[] arr, int offset)
int To Byte Arr 
arr[offset] = (byte) ((0xFF) & (val));
arr[offset + 1] = (byte) ((0xFF) & (val >> 8));
arr[offset + 2] = (byte) ((0xFF) & (val >> 16));
arr[offset + 3] = (byte) ((0xFF) & (val >> 24));
byte[]int32ToByteArray(int a)
int To Byte Array 
byte[] ret = new byte[4];
ret[0] = (byte) (a & 0xFF);
ret[1] = (byte) ((a >> 8) & 0xFF);
ret[2] = (byte) ((a >> 16) & 0xFF);
ret[3] = (byte) ((a >> 24) & 0xFF);
return ret;
byte[]int32toByteArray(int i)
intto Byte Array 
byte[] output = new byte[4];
output[0] = (byte) ((i & 0xFF000000) >> 24);
output[1] = (byte) ((i & 0x00FF0000) >> 16);
output[2] = (byte) ((i & 0x0000FF00) >> 8);
output[3] = (byte) (i & 0x000000FF);
return output;
byte[]int32ToByteArray(int integer)
int To Byte Array 
return new byte[] { (byte) integer, (byte) (integer >> 8), (byte) (integer >> 16), (byte) (integer >> 24) };
byte[]int32ToByteArray(int value)
Converts an int32 into a 4 byte array 
return new byte[] { (byte) (value >> 24 & 0xFF), (byte) (value >> 16 & 0xFF), (byte) (value >> 8 & 0xFF),
        (byte) (value >> 0 & 0xFF) };
voidintegerToByteArray(final int integerToSerialize, final byte[] byteArray, final int offset)
Serializes and writes the given integer number to the provided byte array. 
for (int i = 0; i < 4; ++i) {
    final int shift = i << 3; 
    byteArray[offset + 3 - i] = (byte) ((integerToSerialize & 0xff << shift) >>> shift);
voidintegerToByteArray(int a, byte[] buf)
Converts an integer to a byte array with a length of 4. 
buf[0] = (byte) ((a >> 24) & 0xFF);
buf[1] = (byte) ((a >> 16) & 0xFF);
buf[2] = (byte) ((a >> 8) & 0xFF);
buf[3] = (byte) (a & 0xFF);
byte[]integerToByteArray(int value)
Take the given int value and convert it into a byte array suitable for sending over the network. 
return new byte[] { (byte) (value >>> 24), (byte) (value >>> 16), (byte) (value >>> 8), (byte) (value) };
intIntegerToBytes(int i, byte[] dst, int offset)
Integer To Bytes 
return IntegerToBytes(i, dst, offset, true, true, false);
