Java Start/Stop System process and also check if it is running or not

This  block of code detects if mysql  database process  is running or not

String line;

try {
            Process proc = Runtime.getRuntime().exec("wmic.exe");
            BufferedReader input = new BufferedReader(new InputStreamReader(proc.getInputStream()));
            OutputStreamWriter oStream = new OutputStreamWriter(proc.getOutputStream());
            oStream .write("process where name='mysqld.exe'");
            oStream .flush();
            oStream .close();
            while ((line = input.readLine()) != null) {
                // Here detects if mysqld process is running
            }
            input.close();
        } catch (IOException ioe) {
            ioe.printStackTrace();
        }

  This block of code starts mysql service

Process p = new ProcessBuilder("c:/mysql/bin/mysqld", "").start();

  And  you may use 

p.destroy();

if you want to Stop it
