title: How to add multiple children in a list into a pane in Java FX
body: <p>I am trying to create multiple objects and then put those into my scene. For this I am using a loop to create new object in each iteration and insert that into the list.</p>
  
  <pre><code>//single object
  robot = new Circle(25, Color.BLUE);
  robot.relocate(getRandomCoordinates(600), getRandomCoordinates(400));
  
  ArrayList&lt;Circle&gt; particles = new ArrayList&lt;Circle&gt;();
  
  //multiple objects in list particles
  for(int i = 0; i &lt; 10; i++)
  {
    particles.add(new Circle(10, Color.GREEN));
  }
  </code></pre>
  
  <p>Now the main issue is how can I insert the list of objects into my pane. For a single object I am using this:</p>
  
  <pre><code>playground.getChildren().addAll(robot);
  </code></pre>
  
  <p>How can I add the list of objects into my Pane - playground ?</p>
  
  <p>Thanks!</p>
