The makeMenuItem method creates a new JMenuItem object with a specified menu label. The doSomethingElse method is called when the JMenuItem object is clicked. The MyMenuListener class implements the ActionListener interface, which defines the actionPerformed method. The actionPerformed method is called when the JMenuItem object is clicked. The doSomethingElse method is called from the actionPerformed method. Therefore, the doSomethingElse method can be called at most four times when the makeMenuItem method is called four times.
