Answer / m. abhishek

yes, but u require type casting because the the binary
operation in java should atleast returns Integer values

example :
byte a=12;
byte b=23;
// byte c=a+b; //Not OK,bcoz a+b is an int value
int c=(byte)a+b; // OK

Answer / ashish ranjan

No We cannot add two byte variables directly. The reason behind is the operator '+' is used to perform integer operation. so the variables are automatically promoted to the integer when we perform any arithmetic operation.

so we need to typecast the variables

b= (byte)(b1 + b2);
