Error with variable

Question

Hi
I wrote a program that is supposed to call a method that returns 21 numbers with doubles from the user, then the program is supposed to call a method that displays the highest and lowest numbers entered as well as the average of the numbers. But... I get 2 errors that say cannot resolve symbol for lines 17 and 18 (which is this part number(arrays) and display(arrays) and another one that says cannot resolve symbols for line 40 int average = numbers.getAverage(); heres the program
import javax.swing.JOptionPane;
import java.util.*;
public class array
     public static void main (String [] args)
          number(arrays);
          display(arrays);
          int[] numbers = new int[21];
     public static double number(int[] numbers)     
          for(int i = 0; i < numbers.length; i++)
          numbers[i] = Integer.parseInt(JOptionPane.showInputDialog("Choose a number"));
     public static double display(int[] numbers)
          Arrays.sort(numbers);
          System.out.println(numbers[0] + "is your lowest number");
          System.out.println(numbers[21] + "is your highest number");
          int average = numbers.getAverage();
     System.exit(0);
}thanks

Answer 1

you loop through and assign the numbers in numbers to
a variable called sum then divide by numbers.length,
would that be how you do it?It might just be a case of sloppy wording, but as written, no, that's not quite what you'd want to do.
for (...) {
    sum = numbers[ix];
} That's what your wording says to me. That may not be what you meant, but if it is, try it and see what happens.
