Java是否对事件有本机支持,类似于C#？

// 事件类
public class MyEvent {
    private String message;

    public MyEvent(String message) {
        this.message = message;
    }

    public String getMessage() {
        return message;
    }
}

// 监听器接口
public interface MyListener extends EventListener {
    void onEvent(MyEvent event);
}

// 事件源
public class MyEventSource {
    private List<MyListener> listeners = new ArrayList<>();

    public void addMyListener(MyListener listener) {
        listeners.add(listener);
    }

    public void removeMyListener(MyListener listener) {
        listeners.remove(listener);
    }

    public void triggerEvent(MyEvent event) {
        for (MyListener listener : listeners) {
            listener.onEvent(event);
        }
    }
}

// 监听器实现
public class MyListenerImpl implements MyListener {
    @Override
    public void onEvent(MyEvent event) {
        System.out.println("Event received: " + event.getMessage());
    }
}

// 使用示例
public class Main {
    public static void main(String[] args) {
        MyEventSource eventSource = new MyEventSource();
        MyListener listener = new MyListenerImpl();
        eventSource.addMyListener(listener);
        eventSource.triggerEvent(new MyEvent("Hello, world!"));
    }
}
