How do I split an integer into 2 byte binary?

Question

Given

private int width = 400;
private byte [] data = new byte [2];  

I want to split the integer \"width\" into two bytes and load data[0]

Answer 1

To get the high byte, shift right by 8 bits then mask off the top bytes. Similarly, to get the low byte just mask off the top bytes.

data[0] = (width >> 8) & 0xff;
data[1] = width & 0xff;
