How to add selection listener in Java?

In Java, you can add a selection listener by following these steps:

  1. Create a selection listener class that implements the java.awt.event.ItemListener interface and overrides its itemStateChanged method.
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;

public class MyItemListener implements ItemListener {
    @Override
    public void itemStateChanged(ItemEvent e) {
        // 处理选择事件的逻辑
    }
}
  1. Add a listener to a component that requires one, such as a checkbox (JCheckBox).
JCheckBox checkBox = new JCheckBox("Check me");
checkBox.addItemListener(new MyItemListener());

In this way, when the user clicks on the checkbox, it will trigger the itemStateChanged method in MyItemListener, thereby executing the corresponding logic.
