Java invokes DOS and obtains output of bat in execution

String s; Process process; try {process = Runtime.getruntime (). EXEC ("cmd/c d://test.bat"); InputStream In=process.getinputstream (); BufferedReader BufferedReader = new BufferedReader (new InputStreamReader (in)); while ((S=bufferedreader.readline ())!= null) {System.out.println ("SSS" +s);} in.close (); Bufferedreader.close (); catch (IOException e) {e.printstacktrace ();}

This way, although we can't get the bat from the Java program if it's done, we can tell if the bat is over by the last printed information through the bat.

Also, so that Java can get the information printed in the Java main function in the bat called through System.out.print and in the bat, through the Echo
