如何cmd.exe从java启动？ [英] how can cmd.exe be launched from java?

问题描述

in .net如果我想打开一个新的命令行窗口，我可以写。

in .net if I wanted to open a new command line window, I could just write.

     System.Diagnostics.Process.Start("cmd.exe");

但是，以下代码不执行任何操作：

in java, however, the following code does nothing:

    new java.lang.ProcessBuilder("cmd.exe").start();
    java.lang.Runtime.getRuntime().exec("cmd.exe");

没有创建新窗口，并且任务管理器中不显示任何进程。

No new window is created and no Process appears in Task Manager.

现在如果我试图打开的应用程序是notepad.exe，然后java会打开它只是很好。

Now if the application I was trying to open was "notepad.exe", then java would open it just fine.

？

推荐答案

Runtime.getRuntime().exec(new String[]{"cmd.exe","/c","start"});

至了解更多开始，在命令提示符下键入 help start 。
