Question

What I’m trying to do is run 60 trials of this program. Each time I want the value of K to go down 1, until K=0. Currently i have only been able to get the program to repeat the same answer 60 time.

   package heatloss;

/**

public class HeatLoss {

    public static void heatloss(double x, double m, double a, double k) {
    double heatloss = x - m * (x - a);
    if (k == 0) {
    System.out.println("Done With Trials");
    }
        else {
    System.out.println(heatloss);
    heatloss(x,m,a,k-1);
    }
    }


    public static void main(String[] args) {
        double k = 60;
        double old = 60+k;
        double m = 0.10;
        double air = 40;


    heatloss(old, m ,air, k-1 );
    }
}

Answer 1

The value of k is decreasing, because your function runs 60 times, as you said. However:

heatloss = x - m * (x - a);

is a constant value, because it does not relate tok in any way, and thus

System.out.println(heatloss);

prints the same value every time.
