用JAVA写出源代码。运行结果如下？
您好：代码及运行结果如下，源码供参考：

如何反编译java的源码源码文件？
需要准备的工具：电脑，反编译工具ILSpy。源码1、源码首先在百度上搜索下载反编译工具ILSpy，源码解压后如图，源码其他软件如何打开网页源码双击.exe文件打开解压工具。源码
2、源码选择file选项，点击“打开”。手机会员卡系统源码错误
3、接着选择要反编译的文件，点击“打开”。
4、h5视频播放器源码这是会出现一个对话框，在这个对话框里面就可以看到源码了。
5、如果想把源码保存下来，自己在源码的基础上修改，点击"file"下的“Save code...”,保存即可。
6、如需用vs打开反编译后的源码，只需要打开这个.csproj文件即可。
