Creator follows any design pattern, If it is then what kind of design pattern it follows.Because it creates all the files and giving the developer luxury of drag and drop the component and do some alignment.
Is Creator giving the flexibility to implement our own design patterns.Take the example of Front Controller Pattern. Will it be possible to implement when we use the Creator.Pl explain.Because now a days it is very important.
Java Studio Creator heavily relies on JSF (Java Server Faces) which itself is an MVC2 framework. See http://java.sun.com/developer/technicalArticles/GUI/JavaServerFaces/ and the FacesServlet API (http://java.sun.com/j2ee/javaserverfaces/1.1/docs/api/index.html)
So yes, Creator integrates design patterns although Corporate Developers shouldn't have to worry about these. More advanced developers can always use other design patterns or frameworks as the underlying NetBeans infrastructure for Creator lets you do pretty much anything you want (if you need to).
