Is it possible to execute binary files in java?
提问by Dimitri
I have a list of binaries written in Java, Ada, C, and Python and I want to execute them. How can I do that? Are there any JVM binding to those languages?
我有一个用 Java、Ada、C 和 Python 编写的二进制文件列表，我想执行它们。我怎样才能做到这一点？是否有任何 JVM 绑定到这些语言？

If all you want to do is execute existing applictions, you can use the execmethods from the java.io.runtimenamespace.
如果您只想执行现有应用程序，则可以使用命名空间中的exec方法java.io.runtime。
Runtime rt = Runtime.getRuntime();
Process ps = rt.exec("path to my executable.exe");

Yes. Here is a link to a good blog article on how to do it: Running system commands in Java.
是的。这是一篇关于如何做到这一点的优秀博客文章的链接：在 Java 中运行系统命令。
The gist of it is that you need to do the following:
其要点是您需要执行以下操作：
// run the Unix "ps -ef" command
// using the Runtime exec method:
Process p = Runtime.getRuntime().exec("ps -ef");
You can pretty much put any command in there but the only gotcha that I have encountered in be aware of system environment variables like the PATH that you are running your JVM in.
您几乎可以在其中放置任何命令，但我遇到的唯一问题是要注意系统环境变量，例如您正在运行 JVM 的 PATH。

If you want to interact with the binary API's, use:
如果要与二进制 API 交互，请使用：
- Java Native Access (JNA): for loading and calling DLLs.
- Java Native Interface (JNI): for wrapping a C library in Java.
- Java Native Access (JNA)：用于加载和调用 DLL。
- Java Native Interface (JNI)：用于在 Java 中包装 C 库。
