Open Command Prompt from Java

Question

I have the following code to open a command prompt window Runtime.getRuntime().exec("cmd.exe /c start");, but I'm trying to open the prompt with a different location loaded into it.

The idea behind the program is to allow the user to choose one of 3 options to load the command prompt window into, and they're mounted on different locations for example two of them are X:/myJava/ and H:/publicJava/.

How can I open the command prompt window that is loaded into these folders once the user makes their choice?

Answer 1

Use this Runtime.getRuntime().exec("cmd.exe /c start", null, new File("X:/myJava"));

Answer 2

You can use making a batch file with commands like x: cd publicJava

and then execute that batch file using the Runtime.getRuntime().exec("myBatch.bat");

Answer 3

Try this

Runtime.getRuntime().exec("cmd.exe /c start /d d:\\java");

The start command accepts a path via the "/d" switch. Keep in mind that you have to escape the backwards slash in the path, hence the double slash.

• Blease: I managed to figure it out and got it to work with this Runtime.getRuntime().exec("cmd.exe /c start", null, new File("X:/myJava"));
• Ali Cheaito: I updated my answer to include the Java bit. That will work for you without the need to create a File instance. Though it's not that big of a deal.
