title: Passing and copying arrays?
body: <p>I am trying to create two Arrays in main then call a method where the values of the first array(which I randomized) are copied to the second array,I am getting stuck at calling the method and passing. I am lost on how to call and pass arrays 
  any help would be appreciated. </p>
  
  <pre><code>class C9hw5 
  
   {
  
     public static void main(String[] args)
       {
  
          int[] ar = new int[10]; // random array
  
          int[] at = new int[10]; // array two
  
          Random r = new Random();
  
          for(int i = 0; i &lt; ar.length; i++) // initializing it to random
  
           ar[i] = r.nextInt();
  
          System.out.println("The random array displays");
  
          for(int i = 0; i &lt; ar.length; i++)
  
           System.out.println( ar[i]);
  
          copyArray();
       }
  
     public static void copyArray(int ar[], int at[])
  
       {
  
          for (int i = 0; i &lt; at.length; i++) 
  
              at[i] = ar[i];
  
  
       }
    }
  }
