有一个java小程序，是贪吃蛇游戏，如何往里面添加声音代码呢，让声音在“Gameover”的时候播放
这个设置好的没办法做；如果真的要做的话那么就相当于重做一个游戏了，你想想看真的有这样的善人吗？所以还是现实点吧朋友你就凑合着玩就好了如何？

怎么包装贪吃蛇项目
思路：
首先你要有一条贪吃蛇，哎，就是玩儿。
1.先用Java敲一个贪吃蛇小游戏的程序。
2.把Java程序打包成jar文件包，把jar包打包成exe应用程序
知道思路以后，接下来按照我的详细步骤走，能少踩坑，别问我怎么知道的！！！
一、Java“敲一个”贪吃蛇小游戏
废话不多说，本篇主要讲从java项目到exe应用程序，Java项目的代码在我上传的资源当中——代码-greedy snack.zip
二、将项目打成jar包
如何打包成jar包？
1.手动打可直接执行的jar包（本次不使用）2. 使用intellij idea工具打可直接执行的jar包
1) 打开项目
2）点击 File — 选择 Project Structure，找到“Artifacts” 点击 “+” 选择“JAR” —“Empty”。
3) Name栏可以填入自定义的名字，Output ditectory选择jar包生成目标目录，Available Elements里双击需要添加到jar包的文件，即可添加到左边的jar包目录，如图：
4）点击Create Manifest，选择放置MANIFEST.MF的文件路径，直接默认项目根目录就行，点击OK。
5） 点击Main Class后面选择按钮， 弹出框中选择需要运行程序入口main函数，点击OK，点击OK。
6） 点击菜单中“Build” - "Build Artifacts"， 双击弹出框中待生成jar包下面的build即可，如下图
7）至此使用Intellij idea生成可直接执行jar包就完成了。
8）查看生成的jar包,并运行jar包。命令行运行jar包
java -jar xxx.jar
复制代码
三、打包成为exe应用程序
这里首先你要有：
上面生成的jar包 greedy snack.jar
工具：exe4j，一个将jar转换成exe的工具 链接：… 提取码：ijdv
1）安装exe4j,打开安装好的exe4j,进行注册
注册码：L-g782dn2d-1f1yqxx1rv1sqd
2) 点击 Next, 选择JAVA转EXE
3) Next，填入自定义的名字和生成目标文件目录
4) 继续Next，选择启动模式、设置程序名称和程序图标
5） 下方有个选项，需要设置打包后的程序兼容32和64位系统。
勾选,然后Next。
6）然后Next，直到出现如下界面，开始选择jar包以及配置
在VM参数配置的地方加上：-Dfile.encoding=utf-8
添加jar包
设置启动类
Next 配置JRE
Next 选择 Client VM
7）Next 直到如下图界面
桌面多了一个贪吃蛇小游戏3.0.exe文件，至此我们就成功的做出了一个Java贪吃蛇小游戏的exe应用程序
