how to get node path from JTree when tree is clicked?

I have tree with several nodes and also create one tree listener for that,now i need to get the specific node path when it is clicked, I have tried this code but didn't get exact output can anybody help me?

public class FTListener implements TreeSelectionListener {


    @Override
    public void valueChanged(TreeSelectionEvent e) {
        TreePath[] tree=new TreePath[e.getNewLeadSelectionPath().getPathCount()];
        int i=0;

        tree=e.getPaths();

        for(TreePath tr:tree){
            System.out.println(tree[i]);
        i++;}

        //getPath() returns the array elements so i'm here using 
    //for loop for printing each elements.

this is the output

Do this

public void valueChanged(TreeSelectionEvent e) {

    DefaultMutableTreeNode node = (DefaultMutableTreeNode)
                       tree.getLastSelectedPathComponent();

    if (node == null) {
    //since Nothing is selected.     
     return;
    }

    Object nodeObject = node.getUserObject();
    System.out.println("Selected node : " + nodeObject);
}

Add this if you want only single selection

tree.getSelectionModel().setSelectionMode
        (TreeSelectionModel.SINGLE_TREE_SELECTION);
