Convert int to byte array

I need a way to do this

String username = "Snake";
int usernameLength = username.length(); // 5

converting it to

0x05

Should I use a for loop to get each number and add a zero if the result is less than two numbers?

Try the ByteBuffer class...

byte[] byteArray = ByteBuffer.allocate(1).putInt(username.length()).array();
