Questions 6 - 9 Refer to the following code: public class WhatsIt { private int[] values; private double average; public WhatsIt () { values = new int[10]; findAvg(); } public WhatsIt (int[] n) { values = n; findAvg(); } public void findAvg () { double sum = 0; for (int i = 0; i < values. length; i++) { sum += values[i]; } average = 1.0 * sum / values. length; } public String toString() { return "Average: " + average + " Length: " + values. length; } } What does the line findAvg(); in the constructor do? Creates a reference to the average variable. Calls the method findAvg() so the variable average is updated correctly. Calls the constructor findAvg; so the object can be created in memory. This call should be removed. Checks to see if the average variable has been initialized

class WhatsIt

{

private static int [] values;

private double average;

public Double Average=average;

public WhatsIt () {values = new int [10]; findAvg(); }

public WhatsIt (int [] n) {values = n; findAvg(); }

public static void findAvg ()

{double sum = 0;

for (int i = 0; i < values.length; i++)

{sum += values[i]; }

average = 1.0 * sum / values.length;

System.out.println(Average);

System.out.println(average);

}

public static String ToString()

{

   System.out.println(average); System.out.println(values.length);

   return "Average: " + average + " Length: " + values.length;

}

public static void main(String[] args)  

{

    //WhatsIt();

    //ToString();

    findAvg();

}

}

The findAvg() calculates the average.

The reference to average is defined as below:

public double Average=average;

And when we call findAvg average is initialized, and Average is also initialized, which we can check through println statement.
