catch(InterruptedException ie)

I can't get output

Answer 1

I have done a similar thing: try to make a mehotd that
return an output String.
String output = new String();
String cmd = /* all that you want */ "";
Process p = Runtime.getRuntime().exec(cmd);
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
while ((line = input.readLine()) != null) {
output += line + "\n";
returning the output variable
