Description

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

Method

byte[]intToByteArray(int value)
Convert the specified int to a 4 byte array. 
byte[] b = new byte[4];
for (int i = 0; i < 4; i++) {
    int offset = (b.length - 1 - i) * 8;
    b[i] = (byte) ((value >>> offset) & 0xFF);
return b;
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)
Converts an integer value to a byte array. 
byte[] bytes = new byte[INT_BYTE_ARRAY_LENGTH];
bytes[0] = (byte) (value >> 24);
bytes[1] = (byte) (value >> 16);
bytes[2] = (byte) (value >> 8);
bytes[3] = (byte) (value);
return bytes;
byte[]intToByteArray(int value)
int To Byte Array 
return intToBytes(value);
byte[]intToByteArray(int value)
int To Byte Array 
byte[] result = new byte[4];
result[3] = (byte) (value >>> 24);
result[2] = (byte) (value >>> 16);
result[1] = (byte) (value >>> 8);
result[0] = (byte) value;
return result;
byte[]intToByteArray(int value)
int To Byte Array 
byte[] bytes = new byte[4];
intToByteArray(bytes, 0, value);
return bytes;
byte[]intToByteArray(int value)
Converts the given integer value into a byte array. 
return new byte[] { (byte) ((value >>> 24) & 0xFF), (byte) ((value >>> 16) & 0xFF),
        (byte) ((value >>> 8) & 0xFF), (byte) (value & 0xFF) };
voidintToByteArray(int value, byte[] buffer, int offset)
Convert the provided into into a byte[] and write the values into the given buffer starting at the provided offset (this will take up 4 bytes!) 
buffer[offset] = (byte) (value >>> 24);
buffer[offset + 1] = (byte) (value >>> 16);
buffer[offset + 2] = (byte) (value >>> 8);
buffer[offset + 3] = (byte) (value);
byte[]intToByteArray(int value, byte[] data, int offset)
int To Byte Array 
if (data == null)
    data = new byte[4];
int temp = Math.abs(value);
for (int i = 0; i < 4; i++) {
    data[offset + i] = (byte) (temp % 256);
    temp = temp / 256;
    if (i == 0 && value < 0)
        data[offset] = (byte) (~data[offset] + 1);
...
voidintToByteArray(int value, byte[] dest)
int To Byte Array 
int lastIndex = dest.length - 1;
for (int i = lastIndex; i >= 0; i--) {
    dest[i] = (byte) (value & 0xff);
    value = value >> 8;
