Send Ctrl+C to a proccess started within java

Question

I want to be able to kill a ping started from my java program, but I need to get the pid to do so. I also did some research and I found out that I can use SendSignal.exe to send Ctl+C, but I need the pid of the process that I have just started. Is there a way in Java to get the pid?

    Process p = null;
    InputStream processOutput;
    BufferedReader reader = null;
    String line = " ";

    p = Runtime.getRuntime().exec("cmd /c " + command);
    processOutput = p.getInputStream();
    reader = new BufferedReader(new InputStreamReader(processOutput));
    // Read the input
    while((line = reader.readLine()) != null){
        output += line + "\n";
        System.out.println(line);

    }

Thank you. That helped me. Not sure why I didn't see it during my google search. — Ducksauce88, Jul 03 '14 at 19:15
Not really a duplicate of that question, as this question is about the PID of a child process rather than the PID of the current process. — Raedwald, Jul 03 '14 at 21:58

Runtime.exec(...) returns a Process object. Would it help if you called process.destroy()?
