A `JRadioButton` is a Swing UI control that allows the user to select one option from a group of options. Only one `JRadioButton` in a group can be selected at a time. When a `JRadioButton` is selected, it is typically indicated by a dot inside the radio button.
To use `JRadioButton` in your program, you need to create a `ButtonGroup` to group the radio buttons together. Then, create the `JRadioButton` objects and add them to the button group. Finally, add the button group to the parent container.
Here's an example code snippet:
```
ButtonGroup group = new ButtonGroup();
JRadioButton radioButton1 = new JRadioButton("Option 1");
JRadioButton radioButton2 = new JRadioButton("Option 2");
group.add(radioButton1);
group.add(radioButton2);
parentContainer.add(radioButton1);
parentContainer.add(radioButton2);
```
In this example, `radioButton1` and `radioButton2` are two radio buttons that are added to the `group`. The `group` is then added to the `parentContainer`. This ensures that only one radio button in the group can be selected at a time.
