(Displaying Events) It's often useful to display the events that occur during the execution of an application. This can help you understand when the events occur and how they're generated. Write an application that enables the user to generate and process every event discussed in this chapter. The application should provide methods from the ActionListener, ItemLi stener, ListSelec-tionListener, MouseListener, MouseMotionListener and KeyListener interfaces to display messages when the events occur. Use method toStri ng to convert the event objects received in each event handler into Strings that can be displayed. Method toString creates a String containing all the information in the event object.
