how to run a superuser commands via java program.?

[cooldharma06]

hi all,
i want to run the superuser commands via java program.

public static void main(String a[]) throws IOException
	{
         try {
        	 Process p = Runtime.getRuntime().exec("ifconfig -a");
        	 BufferedReader in = new BufferedReader(
        	                                 new InputStreamReader(p.getInputStream()));
        	 String line = null;
        	 while ((line = in.readLine()) != null) {
        	                 System.out.println(line);
        	 }
        	 } catch (IOException e) {
        	 e.printStackTrace();
        	 }
	}

For normal commands like "ls" these things are working. but for super user commands its not working.
i am running these things from IDE.
Anybody know the way to solve this one.?!!
