title: Checking if JTree node exist using path
body: <p>I have a classic JTree populated with some nods. Lets assume tree looks like this:</p>
  
  <pre><code>Root
  |-Fruit
  |--Apple
  |--Orange
  |-Objects
  |--Table
  |--Car
  </code></pre>
  
  <p>Is there any way in java to check if node exists using assumed path like this:</p>
  
  <pre><code>TreeNode found = model.getNodeOrNull("\\Fruit\\Apple")
  </code></pre>
  
  <p>so if node in given location exists it's returned, if not null is returned? Is there any such mechanism in Java?</p>
