I'm trying to print an array which is returned from a method, but I get the error [D@6521f956 in the terminal. As you can see from the code below, I am looping through my array to calculate Body Mass Index, which I then again put in a new array. It is this array which I am trying to return to my main method and print in the terminal, so far with no luck. Anything obvious I'm doing wrong?

public class Method {

    double [] bmiCalculation (double [] height, int [] weight){
    double [] bmiArray = new double[height.length];

    for (int i = 0; i < height.length && i < weight.length; i++) {

      double bmi = weight[i] / (height[i] * height[i]);
      bmiArray[i] = bmi;
    }

    return bmiArray;
  }
}

class Methodmain {

  public static void main (String [] args) {

    Method method = new Method();
    double [] heightArray = {1.78, 1.67, 1.59, 1.80, 1.90};
    int [] weightArray = {50, 60, 70, 80, 90};

    System.out.println(method.bmiCalculation(heightArray, weightArray));
  }
}

That's not an error - that's just what you get when you print out a double[] because arrays in Java don't override toString().

Just use Arrays.toString(double[]) instead:

double[] result = method.bmiCalculation(heightArray, weightArray);
System.out.println(Arrays.toString(result));
