Question

I have some simple java code to call a method with a value to calculate the volume. I just get error like missing ; in JCreator? What is wrong? This is new beginners non object programming level course. Therefore i guess there should be no public static in the method?

public class Matematik {

public static void main(String[] args) {

System.out.println(volym(10));

    double volym(int tal){

    return round((4 * math.pi * math.pow(tal,3) / 3),2);

    }

}

}

Answer 1

The declaration for volym should not be in main:

public class Matematik {

    public static double volym(int tal){

        return round((4 * math.pi * math.pow(tal,3) / 3),2);

    }

    public static void main(String[] args) {

        System.out.println(volym(10));

    }
}

Edit: it’s worth noting that you have other issues too. Namely, java.lang.Math.PI (note the casing) and Math.pow. And Math.round….
