How could I pass in commands into a terminal that is already running in java (linux)

Question

I have been researching how to run a terminal command in java. I am doing this to make a program I can use to ssh into another pc (just as a project). How could I keep continuing putting commands in this terminal? If I run this I get a message to put in my password and if I do so it will print out what the messages the terminal spits out at the : while((line = in.readLine()) != null){ System.out.println(line + "\\n");
} while((line = in.readLine()) != null){ System.out.println(line + "\\n");
}

line, but a few seconds after that my program will stop working. I currently have a GUI that is just a button and if I press the button it will run this code. Could someone help me to fix the issue of it stopping and give me information on how I could continue to put commands into the terminal? Thanks.

    Process p = null;
    String[] command = {"/bin/sh",  "-c", "ssh 192.168.2.100"};
    ProcessBuilder pb = new ProcessBuilder(command);

    String line = null;

    try {
        term = pb.start();
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

    InputStream is = p.getInputStream();

    BufferedReader in = new BufferedReader(new InputStreamReader(is));

    try {
        while((line = in.readLine()) != null){
            System.out.println(line + "\n");    
        }
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    try {
        in.close();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

You can not pass the argument to live JVM, But there is way in which you can modify the some of the parameters which done using JMX , with this you can connect to live JVM and send the parameters. which will be taken the effect immediately.

Hope that helps
