How to kill a system process from java code.

Question

Hi,
i need to kill or remove windows system process like cmd.exe from java code.
like removing it from end process in task mgr.
i tried below code but its not removed.
is there a better way we can do this.
killing a system process from java code will create any issues?
   public static void main(String[] args) throws Exception {
   String[] cmd = { "cmd.exe" };
   Process p = Runtime.getRuntime().exec(cmd);
   p.destroy();
any suggestions or ideas are really appreciated.
thanks.

Hi  jtahlborn, mohan
yes the process is created from my java code. 
in my code iam creating a process like below and if it is running for a long i need to kill it from java.
For that " Runtime.getRuntime().exec("taskkill /F /PID " +  7408); " is working fine.
7408 is my process id in taskmgr created from java and iam manually passing the PID it to kill it.
But i need to get the PID from java code.
Thanks for your suggestions.
Sample Code:
public static void main(String args[])
        try {
          Process process = Runtime.getRuntime().exec(new String[]{"cmd.exe","/c","start"});        
          Field f = process.getClass().getDeclaredField( "handle");
          f.setAccessible( true);         
          long procHandle = f.getLong( process);
          System.out.println( "prochandle: " + procHandle );
          //Runtime.getRuntime().exec("taskkill /F /PID " +  procHandle);
        } catch( Exception e) {
          e.printStackTrace();
