如何使用事件使方法运行？

const EventEmitter = require('events');

class MyEmitter extends EventEmitter {}

const myEmitter = new MyEmitter();

// 注册事件监听器
myEmitter.on('event', () => {
  console.log('event 触发');
});

// 触发事件
myEmitter.emit('event');

import asyncio

async def main():
    loop = asyncio.get_event_loop()
    loop.create_task(some_method())
    loop.call_soon(some_method)

async def some_method():
    print('some_method 执行')

asyncio.run(main())

import java.util.EventListener;
import java.util.EventObject;

class MyEvent extends EventObject {
    public MyEvent(Object source) {
        super(source);
    }
}

interface MyListener extends EventListener {
    void eventPerformed(MyEvent e);
}

class MyEmitter {
    private MyListener listener;

    public void addMyListener(MyListener l) {
        listener = l;
    }

    public void performEvent() {
        if (listener != null) {
            listener.eventPerformed(new MyEvent(this));
        }
    }
}

class MyAdapter implements MyListener {
    public void eventPerformed(MyEvent e) {
        System.out.println("eventPerformed() 方法执行");
    }
}

public class Main {
    public static void main(String[] args) {
        MyEmitter emitter = new MyEmitter();
        MyAdapter adapter = new MyAdapter();
        emitter.addMyListener(adapter);
        emitter.performEvent();
    }
}
