Integer too long Java
<pre><code>  public static void gramstoAtoms()
  {
   System.out.println("Enter Amount of grams");
   Scanner keyboard = new Scanner(System.in);
   long x = keyboard.nextLong();
   System.out.println("Enter Unit Grams");
   long y = keyboard.nextLong();
   long result = x/y;
   long answer = result*60200000000000000000000;
   System.out.println(answer + "Atoms");
  }
</code></pre>

<p>How do I change this code so that I don't get an integer is too long error?</p>
