如何为从另一个类引发的事件创建事件侦听器

// 事件类
class MyEvent {
    private String eventName;
    private Object eventData;

    public MyEvent(String eventName, Object eventData) {
        this.eventName = eventName;
        this.eventData = eventData;
    }

    // 省略 getter 和 setter 方法
}

// 事件源类
class EventSource {
    private List<EventListener> listeners = new ArrayList<>();

    public void addListener(EventListener listener) {
        listeners.add(listener);
    }

    public void removeListener(EventListener listener) {
        listeners.remove(listener);
    }

    public void fireEvent(String eventName, Object eventData) {
        MyEvent event = new MyEvent(eventName, eventData);
        for (EventListener listener : listeners) {
            listener.onEventReceived(event);
        }
    }
}

// 事件侦听器接口
interface EventListener {
    void onEventReceived(MyEvent event);
}

// 事件侦听器类
class MyEventListener implements EventListener {
    @Override
    public void onEventReceived(MyEvent event) {
        // 处理事件的逻辑
        System.out.println("Received event: " + event.getEventName());
        System.out.println("Event data: " + event.getEventData());
    }
}

// 在使用的地方
public class Main {
    public static void main(String[] args) {
        EventSource eventSource = new EventSource();
        MyEventListener eventListener = new MyEventListener();
        eventSource.addListener(eventListener);

        // 模拟事件发生
        eventSource.fireEvent("Event1", "EventData");

        // 解除事件侦听器
        eventSource.removeListener(eventListener);
    }
}
