As the title says, why do I need an int to store a byte & byte operation. For example,
byte a = -128;
byte d = -0x7f;
byte b = a & d; // <-- error - can't convert from int to byte
I think 8bit & 8bit = 8bit Is that wrong?

Integer promotion. `byte b = (byte) (a & d);` Also, never post code as an image. – Elliott Frisch Mar 17 '17 at 03:14

There is no [tag:operator-keyword] in Java. Don't tag indiscriminately. – user207421 Mar 17 '17 at 03:38
