发送命令进行处理

Question

I wanna to create a programm which starts a Textfield. In the Textfield I can write commands that will start another process.

Example: Textfield: "open firefox olaf" Then the programm start firefox. Olaf is the Signal that the command ends.

My programm compare the Textfield String array with a commands String array and if for example the word "open" equal in both string array the be run in a switch case method the following method "open". thats works good.

My Problem: Now I wanna a command like this: Textfield: "type in firefox www.web.de olaf" The programm should focused on firefox and should typen in firefox "www.web.de", but I don't know how to do this. I don't wanna use the robot class with robot.keyPressed()

Also I wanna to type in the textfield of the websites.

Why I do this? I just wanna learn java and use Voice speeches, so I dont need to type "open firefox olaf". I can just said it;)

if I need to do with C++ it's okay

    public void keyTyped(KeyEvent e) {
    }

    @Override
    public void focusGained(FocusEvent arg0) {  
    }

    @Override
    public void focusLost(FocusEvent arg0) {
        // TODO Auto-generated method stub
    }

}

You can use command line arguments to achieve that.

./firefox www.stackoverflow.com

so u can use the ProcessBuilder to pass it in :

String urlAddress = someJTextField.getText();
ProcessBuilder pb = new ProcessBuilder("/firefox", urlAddress);
pb.start();
