title: Node array toString Java
body: <p>I have a method which returns children of a given Node. All thats inside a Node (instance variable) is a  char character.</p>
  
  <pre><code> public Node[] children(){
  
      return (Node[]) children.toArray(new Node [children.size()]);
   }
  </code></pre>
  
  <p>I want to output those children later. But it only outputs the reference [Lie.gmit.Node;@7d487b8b]. How would I override the toString method ? or should I create a new method for outputing children nodes ?</p>
