How to? multiline label containing exact system command output

Question

Background info: I'm triggering a system command to display memory utilization. As you know, the "free" linux command displays many lines of text one after the other. It is similar to the mem command used in Window$.
I want to have a label displaying the command output as it is: multiple lines. Just like you see it in the console. I want to mirror whatever comes up on console after executing free from java.
Using html tags won't work out for me in this particular situation. It just doesn't do the trick. Still displays the LAST line of command output with or without html tags.
any ideas? it doesn't have to be a label. It can be anything as long as it works.
Again, as it is, it just displays the last line of the command output
//events will trigger every second
Timer t = new Timer(1000, new ActionListener(){
      public void actionPerformed(ActionEvent event)
//determine memory utilization.
        String cmd = "free -m";
    try {
     String line;
     Process p = Runtime.getRuntime().exec(cmd);
     BufferedReader input =
       new BufferedReader
         (new InputStreamReader(p.getInputStream()));
     while ((line = input.readLine()) != null) {
       label.setText(line);
     input.close();
    catch (Exception err) {
     err.printStackTrace();
    t.start();

got it. thanks.
String cmdMem = "free -m -t -o" ;
      try {
        String lineMem ;
        String outputMem = "" ;
        Process procMem = Runtime.getRuntime ().exec ( cmdMem ) ;
        BufferedReader input =
            new BufferedReader
            ( new InputStreamReader ( procMem.getInputStream () ) ) ;
        while ( ( lineMem = input.readLine () ) != null ) {
          outputMem = ( lineMem + "\n" ) ;
          jTextAreaSystemResourcesOutput.append ( outputMem ) ;
        input.close () ;
      catch ( Exception err ) {
        err.printStackTrace () ;
      }
