Hello Hussain,
I found in the sourcecode of JTree the following constructor which might is be helpful for you:
* Returns a <code>JTree</code> with each element of the specified
* <code>Vector</code> as the
* child of a new root node which is not displayed. By default, the
* tree defines a leaf node as any node without children.
* @param value a <code>Vector</code>
* @return a <code>JTree</code> with the contents of the
*          <code>Vector</code> as children of the root node
* @see DefaultTreeModel#asksAllowsChildren
public JTree(Vector value) {
this(createTreeModel(value));
this.setRootVisible(false);
this.setShowsRootHandles(true);
Greetings
