5.3 Swing widgets

Swing GUI components are instantiated and used in the same fashion as AWT GUI components.

5.4 Layout Managers

The Swing environment uses the same LayoutManagers as AWT. Hence java.awt classes are still imported in Swing applications.

5.5 Event Listeners

Similarly, Event Listeners from AWT are also re-used. They were implemented for Swing GUI components. java.awt.event classes continue to be imported. Swing also defines new even listeners, found in javax.swing.event .
