    Default Problem writing data from PrintStream to "Console as Process" and not "console as System.out"

    in Java 8, windows 10, i have a text app, i want to open a console and write something there,

    first try is:

    String [] cmd = {"cmd.exe", "/c", "start"};
    ProcessBuilder f = new ProcessBuilder(cmd);
    f.redirectErrorStream(true);
    Process p = f.start();
    PrintStream printStream=new PrintStream(p.getOutputStream());
    //
    System.setOut(printStream);
    System.out.println("this write in CMD"); //did not work
