          String featureID = request.getParameter("FeatureID");
          String date = request.getParameter("Date");          
          String featureDescription = request.getParameter("FeatureDescription");
          String author = request.getParameter("Author");
          double price = Double.parseDouble(request.getParameter("Price"));
          Product newProduct = new Product(featureID, date, featureTitle, featureDescription, author, price);
          sCart.addProduct(newProduct);
%>shopping cart class code snippet
Vector products = new Vector();
     public void addProduct(Product i)
          boolean productFound = false;
          Enumeration productEnum = getProducts();
          while(productEnum.hasMoreElements())
               Product product = (Product)productEnum.nextElement();
               if(product.getId().equals(i.featureID))
                    productFound = true;
                    product.quantity += 1;
                    break;
          if (!productFound)
               products.addElement(i);

Answer 1

access$ methods are widely used to access private
members of enclosing class from its inner class and
vice-versa. These methods are generated by Java
compiler, not by JVM runtime.
See
http://java.sun.com/docs/books/jvms/second_edition/htm
l/ClassFile.doc.html#80128 for more details about
synthetic class members.
Other questions need more clarification.I will check that link, Regarding the other two questions:
2. What I meant in my interfaces question is that... Say I have a class X that Extends Y and implements A,B
Then if I want to display all the methods and fields of these classes and interfaces in a recursive way, till I reach the Object class, by going to superclass every time, then I understand I can get to class Y simple by
using x.getSuperClass()
but how can I get the interface methods?? and go upwards in that hierarchy??
3. Sub class question is like this - Say I have 3 classes all user defined in the same directory Class A,B,C where A is the superclass of B and C. My class browser is displaying the hierarchy details of A, then is there any way to put in the details of B and C in the same hierarchical display or just display a separate list of subclass that this class has. I am not sure whether I have made it clear still.
(I didnot understnad your reply on changing the class path, can you please explain it in a bit more detail, provided it holds for this question.)
