You can have a look at the Swing Tutorial for JTrees and TreeModels. Do you simply
want to display several trees or is the important part on the manipulation of them?
There are also TreeMaps and TreeSets. What exactly do you want to do?

kind regards,

I want to manipulate tree for example to use Binary search Trees

Binary search trees are already implemented by the classes I mentioned in my
previous reply. Or do you insist on writing your own binary tree implementation?

I'd say: study the topic; design something and implement it. A barebones binary
tree node might look like this (and then some):

public class Node<T> {
   private T data;
   private Node left;
   private Node right;
   //
   public Node(T data) { this(data, null, null); }
   public Node(T data, Node left, Node right) {
      this.data= data;
      this.left= left;
      this.right= right;
   }
   //
   // your methods here ...
}
