C.E because compiler thinks that a and b are int values if u write( byte)a+b..if give run time exception

[namanmishra]

Int + int is always int and cannot be stored in byte

[manomitmitra]

Your explanation is not correct. It's not about range. If you use
byte a = 1;
byte b = 1;
byte c = a + b;
it still shows compilation error. Because byte, char and short, any binary operation will convert to int.
