title: Add elements of one ArrayList to another ArrayList
body: <p>Is it possible to add the elements of one Arraylist to another Arraylist?
  For example if an Arraylist has elements 3,6,3,8,5 in index 0,1,2,3,4,  now I want to add 3,6,3,8,5 to another ArrayList in index 0, is it possible?</p>
  
  <pre><code>ArrayList&lt;String&gt; num = new ArrayList&lt;String&gt;();
   num.add("3");
   num.add("6");
   num.add("3");
   num.add("8");
   num.add("5");
  ArrayList&lt;String&gt; result = new ArrayList&lt;String&gt;();
   for (int i = 0; i &lt; num.size(); i++)
   {
          result.addAll(i,num);   
   }
  </code></pre>
  
  <p>I have tried this but it is not working.
  what i want is when i try <code>System.out.println(result.get(0));</code>
  result must be [3 6 3 8 5].</p>
