title: creating array with elements determined by user/input
body: <p>trying to make an array, and want the elements to be however large the input will be. eventually this should take x amount of numbers, place in an array, and return the average. But first I need to figure out how placing the size of the elements in the array will be done.</p>
  
  <pre><code>import java.util.Scanner;
  import java.util.ArrayList;
  //needs to be an array
  
  public class statsv2
  {
     public static void main (String args[])
      {
          int[] a= new int[5];
          Scanner sc=new Scanner(System.in);
          System.out.println("Please enter numbers...");
          for(int j=0;j&lt;5;j++)
          {
              a[j]=sc.nextInt();
          }
       }
  } 
  </code></pre>
  
  <p>So I essentially want the that '5'(which appears twice) to be however many times the user keeps entering new numbers</p>
