MHB Solving a Program to Take & Average Unknown Number of User Inputs

[smilesofmiles]

I want to alter my program so it can take an unknown amount of elements (user inputs). I want the program to automatically count the numbers the user is inputting up until they hit enter to the next line. I think I got the program to keep track of this but now my output is a bunch of zeros in place of the user numbers. I don't know how to fill the array with the user numbers as well as keep track of the array size. I have attached a screenshot of the output.

Please let me know if I've been unclear. Any help, direction or hints will be greatly appreciated. I feel like I'm really close to solving this.

Thank you! :-)

       double average = calculateAverage(userNumbers);

    }

Never mind, I figured it out. It doesn't stop between 5 and 10 inputs but as long as the user follows the prompt it should be okay.

public static double [] getArrayNumbers(){
       Scanner input = new Scanner(System.in);
       String numbers = input.nextLine();
       String[] strHolder = numbers.trim().split("\\s+");
       double userNumbers[] = new double[strHolder.length];
       
       for(int counter = 0; counter < strHolder.length; counter++){
           userNumbers[counter] = Double.parseDouble(strHolder[counter]);
        }
       return userNumbers;
    }
