Convert short to byte[] in Java
Solution 1:
ret[0] = (byte)(x & 0xff);
ret[1] = (byte)((x >> 8) & 0xff);
Solution 2:
A cleaner, albeit far less efficient solution is:
ByteBuffer buffer = ByteBuffer.allocate(2);
buffer.putShort(value);
return buffer.array();
Keep this in mind when you have to do more complex byte transformations in the future. ByteBuffers are very powerful.
Solution 3:
An alternative that is more efficient:
// Little Endian
ret[0] = (byte) x;
ret[1] = (byte) (x >> 8);
// Big Endian
ret[0] = (byte) (x >> 8);
ret[1] = (byte) x;
