推荐答案

看看复选框和单选按钮"中给出的代码.添加了一个动作侦听器，该侦听器遍历所有组件并搜索选定的组件.您可以使用该代码来实现.

另外，另一种方法是为每个组件实现一个动作侦听器，以处理组件被选中的事件.

祝你好运！

Have a look at the code given at "Checkboxes and Radio Buttons". An action listener is added that traverses all components and searches for the one selected. You can use that code to do it.

Also, another way would be to implement an action listener for each component to handle the event of a component getting selected.

Good luck!
