When we do
byte b1 = (byte) (value & 0xFF);
we keep from int only 1 lower byte and exactly the same can be achieved with
plain cast. See the test below:
public class Main {
public static void main(String[] args) throws Exception {
IntStream.range(Integer.MIN_VALUE, Integer.MAX_VALUE).forEach(value -> {
byte b1 = (byte) (value & 0xFF);
byte b2 = (byte) value;
if (b1 != b2) {
throw new RuntimeException("" + value);
}
});
}
Also tier1 and tier2 are both OK.
