如何在编译结束后发出蜂鸣声？

import os
os.system('echo -e "\a"')

#include<iostream>
#include<windows.h>

int main() {
    std::cout << "\a";
    // 或者使用 Beep 函数
    Beep(440, 1000);
    return 0;
}

import java.awt.Toolkit;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.Timer;

public class Beep {
    public static void main(String[] args) {
        Toolkit.getDefaultToolkit().beep();
        // 或者使用 Timer 类
        int duration = 1000; // 持续时间，单位毫秒
        int frequency = 440; // 频率，单位赫兹
        final int sampleRate = 44100; // 采样率，单位赫兹
        int length = duration * sampleRate / 1000; // 音频长度，单位采样点
        double[] audioData = new double[length];
        for (int i = 0; i< length; i++) {
            audioData[i] = Math.sin(2 * Math.PI * i * frequency / sampleRate);
        }
        final Timer timer = new Timer(duration, new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                Toolkit.getDefaultToolkit().beep();
            }
        });
        timer.setRepeats(false);
        timer.start();
    }
}

echo ^G

echo -e "\a"
