Redirecting output to a text area

Question

I am running a dos command in my java program using the runtime.exec and am wondering how I can capture the output that the program I am running produces and send it to a text area. I read somewhere where you can create a buffered reader and write that directly into my text area but I am not sure how to do this. Can anyone help me on how to do this or a better way to get the output to a text area?
Thank You.

here's a snippet that may help.
public class STDWIN extends JFrame
     Panel p;
     TextArea ta;
     TextField tf;
     public STDWIN()
     p = new Panel();
     ta = new TextArea(10,40);
     tf = new TextField(40);
     Button b = new Button("EXECUTE");
     p.setLayout(new BorderLayout(2,2));
     p.add(ta,BorderLayout.NORTH);
     p.add(tf,BorderLayout.CENTER);
     p.add(b, BorderLayout.SOUTH);
     getContentPane().add(p);
     pack(); show();
     b.addActionListener(new ActionListener() {
     public void actionPerformed(ActionEvent e) {
          doYoThang();
     public void doYoThang()
     try {
          Process p =      Runtime.getRuntime().exec(tf.getText());
     StringBuffer buff = new StringBuffer();
     BufferedReader br = new BufferedReader(
          p.getInputStream());
     while(br.readLine() != null)
          buff.append(br.readLine());
     ta.setText(new String(buff));
     } catch(Exception e) { }
this is very primitive and not stable i'm sure but it should give you an idea of what you want to do.
