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

Integer is 32 bits (=4 bytes) in java, you know?

width & 0xff will give you the first byte, width & 0xff00 >> 8 will give you the second, etc.
