The 1.2 objectives say:
Write code using component, container, and LayoutManager classes of the java.awt package to present a Graphical User Interface with specified appearance and resize behavior, and distinguish the responsibilities
of layout managers from those of containers
� Write code to implement listener classes and methods, and in listener methods, extract information from the event to determine the affected component, mouse position, nature, and time of the event
� State the event classname for any specified event listener interface in the java.awt.event package
So based on item one
you should know all the container and component classes as well as the layout managers.
