java中检测windows进程的问题，新手求教

[WangBo_NLPR]

诸位，最近学习java，写一个小程序，有这样一个问题：

··
程序中检测windows中某个进程是否已经 存在或者运行

在检测后，如果进程存在，则结束该进程
··

请问我应该如何做呢？？？
应该参考哪个类？？？

还望高手指教

[xialeidi]

帮你顶一下

[WangBo_NLPR]

嘿，我再补充仔细一点

比如我打开了记事本

产生进程notepad.exe

我如何在java程序中检测这个进程呢？？

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

C:\WINDOWS\system32>tasklist | find "flashget.EXE"

C:\WINDOWS\system32>tasklist

Image PID session session# RAM used
========================= ====== ================ ======== ============
System Idle Process 0 Console 0 28 K
System 4 Console 0 168 K
SMSS.EXE 800 Console 0 72 K
CSRSS.EXE 852 Console 0 10,116 K
WINLOGON.EXE 876 Console 0 3,132 K
SERVICES.EXE 932 Console 0 2,124 K

这样可行。。。以前写java调用浏览器进程差不多也是这样写的。

[jackmtlee]

大概一定要用到Runtime,ProcessBuilder了。
