------解决方案--------------------

在 XP 下有 tasklist.exe 它会返回当前运行的进程。你再用程序读取这个输出就可以解析查找里面的 notepad.exe.

Process p = Runtime.getRuntime().execute("cmd.exe /c tasklist.exe");

InputStream input = p.getInputStream();

...

我们用 cmd.exe /c tasklist.exe | find "flashget.exe" 这时区分大小写的，不合适，可能要自己用代码不区分大小写的方式去查找 notepad.exe 。


C:\WINDOWS\system32>tasklist | find "flashget.exe"
flashget.exe                4564 Console                 0      8,752 K
