Because of which, Swing has a pluggable look-and-feel architecture. Swing component has Model as a seperate element, while the View and Controller part are clubbed in the User Interface elements. View represents visual representation of the component's data.Ĭontroller takes the input from the user on the view and reflects the changes in Component's data.
