The example contains two JLabels, two JTextFields and a JComboBox. Note, the above screen shows Java Swing JComboBox as an editable type. When the user selects an item in the combo box, we show that in the first text box. We also show the past selected item in the Deselected JTextField. A combo box can show only one item once the drop-down is collapsed. So when the user picks an item, in combo box point of view, one item was selected by the user and one was de-selected (the previous one).

The example contains three components. One is a JLabel which tells in what mode the example is in. The button labelled OFF is the JToggleButton and it will switch the state between Selected & Unselected. The text box tells what kind of the state change is made by the user while he/she clicked the Two-State button last time.
In this example, we will learn how to use AWT CheckboxMenuItem and Menu Separator.
Here, we use our previous example on AWT Menu and change it to create CheckboxMenuItem. We create three checkbox menu items for Circle, Pentagon and Rectangle. In the above picture, we can also see a sunken line running between normal menu items and checked menu items. This line is called a Menu Separator. We create that here as well in this example.
