Hola-
One of my exam prep books gave the following example:
1: byte i = 2;
2: byte j = 3;
3: i = i * j;
Line 3 doesn't compile w/o a cast to byte. If the value is still within the range of a byte why does this happen?
Thanks-

when u multiply two bytes or two shorts java will automatically cast the result to int.That is why u need to type cast the variable i to byte.

Thanks for the info.
Hopefully, that is in the book somewhere.
