Hello,

I can't understand how the following code works.
If I have a signed byte = -1 (1111 1111) and I logical-AND with 0xFF
(1111 1111) how come there is any effect?

Thanks Phil

public class byteTest {
  public static void main(String[] args) {
    byte a = -1;
       
    System.out.println(a);
    System.out.println((a & 0xFF));
    // Output:
    // -1
    // 255
  }
}
