这个是一个典型的Applet,文件名应该是CarRace.java,需要图片作为车子等等,本人也是别人给的,但是还要个.html文件来运行它,代码为:
Applet code="CarRace.class" width=250 height=350
/Applet
请楼主采纳

1 “@”后面的数字越大，重复次数越多
2把上面代码复制，在计算机上保存为.txt文本文件，再改名为 .imy 文件
3 imy 放到手机里的Audio文件夹
4写短信(不是彩信) 写短信时, 插入铃声对象(自定义铃声对象，就是刚才放在audio 里的imy 文件) 并发送, 对方只要是存在这个芯片漏洞，那么则会产生上述所说效果.

你说的java源代码是指编译成的class文件前的java文件。
当我们运行.java文件时，它会被系统编译成.class文件，例如Test.java编译之后就是Test.class，
源文件就是指Test.java文件，
一般部署项目时，有.class文件就可以发布运行了，但是如果想修改这个系统，.class是不能修改的，要有.java文件才能修改
也可以上网去下反编译软件，就是能把.class文件大部分还原成.java文件的工具，但不是100%还原，而且如果不是正版的，小心有毒啊，什么的。
