The biggest difference between a Swing JList and a List View is that the model view controller separation in JList is not there in List View.

Two separate threads of execution can access the control at the same time without the developer having to worry about the threads interfering with one another.
AWT made this possible..was consequently very sluggish.
The extended class then can be observed by other interested classes in other parts of the program.
The registered classes are notified as soon as any change is triggered in the observable class to which the observer class is registered to.
This article shall try to explain the concepts behind the paradigm and how they are used in Java code with simple examples.
