In this example, we have seven JToggleButton components. First 4 is for the Nationality and second three is for the Sex. Here, these toggle buttons act like a radio button. One can also note that there are two groups here. In a group, only one toggle button can stay in Switched ON state. The above picture shows France and Female is in Selected State. Now, we will implement this example.
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.
