Java command line windows 7 how to do?

Question

Java

Hello everyone, I have a question, we can enter all sorts of commands into the Windows command line and they will be executed, let's say I often need to execute the same command, naturally the thought occurred to me (I myself am learning to code in Java), but is it possible to write such a program so that, when pressed, it somehow executes the code on the Windows command line? Maybe I'm complicating it, but I hope you get the point, thanks, I'm waiting for an answer.

The easiest option:

try {
    // Execute command
    String command = "cmd /c start cmd.exe";
    Process child = Runtime.getRuntime().exec(command);

    // Get output stream to write from it
    OutputStream out = child.getOutputStream();

    out.write("cd C:/ /r/n".getBytes());
    out.flush();
    out.write("dir /r/n".getBytes());
    out.close();
} catch (IOException e) {
}
