public JCheckBoxMenuItem(Icon icon)
Icon boyIcon = new ImageIcon("boy-r.jpg");
JCheckBoxMenuItem jCheckBoxMenuItem = new JCheckBoxMenuItem(boyIcon);

public JCheckBoxMenuItem(String text, Icon icon)
JCheckBoxMenuItem jCheckBoxMenuItem = new JCheckBoxMenuItem("Boy", boyIcon);

public JCheckBoxMenuItem(String text, boolean state)
JCheckBoxMenuItem jCheckBoxMenuItem = new JCheckBoxMenuItem("Girl", true);

public JCheckBoxMenuItem(String text, Icon icon, boolean state)
Icon girlIcon = new ImageIcon("girl-r.jpg");
JCheckBoxMenuItem jCheckBoxMenuItem = new JCheckBoxMenuItem("Girl", girlIcon, true);

public JCheckBoxMenuItem(Action action)
Action action = ...;
JCheckBoxMenuItem jCheckBoxMenuItem = new JCheckBoxMenuItem(action);

Unlike the JCheckBox , the icon is part of the label and not a separate device to indicate
whether something is checked. If either the text label or the icon isn't passed to the constructor,
that part of the item label will be set to its default value of empty. By default, a JCheckBoxMenuItem is
unselected.

■ Note Creating a JCheckBoxMenuItem with an icon has no effect on the appearance of the check box
next to the menu item. It's strictly part of the label for the JCheckBoxMenuItem .
