Q:

Java Jtree mouseEvent if nothing is selected

I am trying to figure out how to code a event that, if clicked in a Swing JTree and the mouse does not click anything in the tree, to get a println that says "nothing". 
Say I have a tree 'info_tree' with an AWT.event. Mouwesvent as such:
private void info_treeMouseClicked(java.awt.event. MouseEvent evt) {   
    if(info_tree.getSelectionPath() /*something along the lines of is empty or if ! info_tree.getSelectionPath().isEmpty()*/
       ){system.out.println("Nothing");
      }else{
          system.out.println("Something");
      }
}

I can't find anything to compare a selectedPath or element of a tree. 

A:

You may wish to try
If (info_tree.getSelectionPath()==null)

But,then you may want to switch your output lines around.  Because that as-is is a true/false condition.  If false it'll goto else.  That could solve it as well.
