How are integers cast to bytes in Java?

Question

I know Java doesn\'t allow unsigned types, so I was wondering how it casts an integer to a byte. Say I have an integer a with a value of 255 and I cast the integer to a byte

Answer 1

The following fragment casts an int to a byte. If the integer’s value is larger than the range of a byte, it will be reduced modulo (the remainder of an integer division by the) byte’s range.

int a;
byte b;
// …
b = (byte) a;
