1、PlaySound或者sndPlaySound

在google中一搜索，会出来很多相关例子。

2、从网上搜索、下载、使用第三方的音乐播放代码库。

Q3: 我用Java写了个贪吃蛇的小游戏想在游戏中加入背景音乐等等各种音效应该用什么方法？

背景音乐最简单

首先准备一个背景音乐的音频文件例如：

audio src="./mp3/xx.mp3" controls="controls" preload id="music" hidden /audio

在打开游戏的时候就用JS触发，其他音效也是一样的

先准备好音频文件，当某个节点触发后读取这条对应的音频文件就可以了！

Q4: 我想看看你贪吃蛇游戏中如何添加的背景音乐（代码）

这个简单啊。开一个线程，然后播放音乐就是了。至于用什么语言，平台，不用的语言都大同小异

Q5: 求一段JAVA编写的贪吃蛇小程序源代码

用MVC方式实现的贪吃蛇游戏，共有4个类。运行GreedSnake运行即可。主要是观察者模式的使用，我已经添加了很多注释了。

1、

/*

* 程序名称：贪食蛇

* 原作者：BigF

* 修改者：algo

* 说明：我以前也用C写过这个程序，现在看到BigF用Java写的这个，发现虽然作者自称是Java的初学者，

* 但是明显编写程序的素养不错，程序结构写得很清晰，有些细微得地方也写得很简洁，一时兴起之

* 下，我认真解读了这个程序，发现数据和表现分开得很好，而我近日正在学习MVC设计模式，

* 因此尝试把程序得结构改了一下，用MVC模式来实现，对源程序得改动不多。

* 我同时也为程序增加了一些自己理解得注释，希望对大家阅读有帮助。
