use the `java streams` to combine the `inputstream` from one to the `outputstream` of other. – Ankit Kumar Apr 16 '14 at 11:08

i used these instructions in my code that it returns to me an exception : public static String execCmd(String cmd) throws java.io.IOException { java.util.Scanner s = new java.util.Scanner(Runtime.getRuntime().exec(cmd).getInputStream()).useDelimiter("\\A"); return s.hasNext() ? s.next() : ""; } – user3533570 Apr 16 '14 at 13:01
