Byte This !

[Zac Roberts]

Can anyone explain why I get a compiler error from the byte values but not from the int values:

public class Check { 
 public static void main(String args[]) {
  byte b = -10;
  byte b2 = -b;
  int i = -10;
  int i2 = -i;
 }
}

Thanks-
Zac

because in the statement
byte b2 = -b;
the b is promoted to an int because of the unary - sign, thus -b will be of type int which is not assignment compatible with a byte...

You are correct sir... and by the way... are you going to have some sort of celebration when you hit 2000 posts, kindof like the millenium... maybe you could have some tequila to go along with the JavaRanch cowboy thing...
