Start CMD by using ProcessBuilder

Question

I am trying to start the CMD application in windows by using the following code, but it doesn\'t work as expected. Several examples from different websites shows that \"cmd\

Answer 1

To use it with ProcessBuilder you must separate the commands like this:

final List<String> commands = new ArrayList<String>();                

commands.add("cmd.exe");
commands.add("/C");
commands.add("start");
ProcessBuilder pb = new ProcessBuilder(commands);
pb.start();

Answer 2

You need to use the start command. Actually, even I don't see a new command prompt popping up, but you can check that a new cmd.exe is definitely started using your task manager.

ProcessBuilder pb = new ProcessBuilder("cmd.exe", "/C", "start");

Though, the same functionality can be achieved using Runtime.exec(), and this actually pops up a new command prompt.

Runtime.getRuntime().exec("cmd.exe /C start");
