Java: Reading output from the Console/StdOut

Today I had a small problem. I wanted to start an external C++ console programm with some parameters and get the output back to my Java program.

Here is a code snippet that reads the output from a console program:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {

  public static void main(String[] args) throws IOException {
        String cmd = "cmd.exe /c dir c:\\temp";

        String line;
        Process p = Runtime.getRuntime().exec(cmd);
        BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
        while ((line = input.readLine()) != null) {
          System.out.println(line);
        }
        input.close();
  }
}

The snippet just outputs the received information.
