Question

I wrote a very simple program in java to get used with the use of static keyword.But i am getting the output as 0. I am not able to find the reason for that.I am a beginner in java .Can anyone please suggest a solution,also please do explain why such an problem was encountered …My code is as following :

public class Cube{

    static int length;
    static int breadth;
    static int height;

    public static int volume(final int i, final int j, final int k){
        return length * breadth * height;
    }

    public static void main(final String args[]){
        System.out
            .println("volume of the cube is : " + Cube.volume(10, 20, 30));
    }
}

Answer 1

int fields, static or not, are initialized as 0.

You should multiply your operands (i * j * k) or assign to your static int fields.
