Random throws "error: cannot find symbol" when using byte instead of int [closed]

I got this method called diceThrow which returns a random number limited to the input given:

        public static int diceThrow(int sides){
        Random random = new Random();
        int answ = random.nextInt(sides) + 1;
        return answ;}

My program gives it values from 2 to 100, so for memory's sake I changed it's int types to byte types but it throws:

error: cannot find symbol
byte answ = random.nextByte(sides) + 1;
                  ^

the modified method is like so:

        public static byte diceThrow(byte sides){
        Random random = new Random();
        byte answ = random.nextByte(sides) + 1;
        return answ;}
