Chapter 13.8, Problem 13.20CP

Explanation of Solution

Responding to menu item selections:

• The menu item generates an action event when the user selected it.
• If the user wants to respond to a menu item action event, users have to register an event handler with the control.

Example:

The example for generating an action once the user selects a menu item is shown below:

//create the menu bar.

JMenuBar book = new JMenuBar();

//create the bookmenu.

JMenu bookMenu = new JMenu("Books");

//create the menu item for add book.

JMenuItem addBookItem = new JMenuItem("Add Book");

//create the menu item for cancel book.

JMenuItem cancelBookItem = new JMenuItem("Cancel Book");

//add the menu item to book menu.

bookMenu...
