My code looks like this

import java.util.Scanner;


public class StudentGrades {

public static void main(String[] argv)
{
    Scanner keyboard = new Scanner(System.in);
    byte q1 = keyboard.nextByte() * 10;
}
}

It gives me an error "Type mismatch: cannot convert from int to byte." Why the heck would Java store a literal operand that is small enough to fit in a byte,. into a int type? Do literals get stored in variables/registers before the ALU performs arithmatic operations.
