该帖子解释了如何在Windows机器上运行所有PID：你必须将 cmd 调用的输出与PID进行比较而不是打印它。

That post explains how to get all PIDs running on a Windows machine: you'd have to compare the output of the cmd call with your PID, instead of printing it.

如果您使用的是类Unix系统，则必须使用 ps 而不是 cmd

If you're on Unix-like systems you'd have to use with ps instead of cmd

从java代码调用系统命令不是一个非常便携的解决方案;然后，流程的实施因操作系统而异。

Calling system commands from your java code is not a very portable solution; then again, the implementation of processes varies among operating systems.
