Java: Open console programmatically and execute commands from it

I need to programmatically open a console (in windows) and from there I need to execute a large command in the console just created. I tried to write to the output stream but had no luck. Here is the code I have thus far to bring up the console.

File fileOne = new File(args[0]);     

String[] command = { "cmd", "/c", "Start"};
ProcessBuilder procBuilder = new ProcessBuilder(command);
procBuilder.directory(fileOne);
Solution

  • Here is an example I used to create a launch icon for a program.

    Runtime rt = Runtime.getRuntime();
    rt.exec("cmd.exe /c cd \""+"c:\\CombineImages\\"+"\" & start cmd.exe /k \"java -Xms1G -Xmx1G jar CombineImages.jar\"");

    Put that code in your main method and replace with whatever command you want to run.
