Ignoring synchronization issues you could do something like this:

  private class MessagePrinterTask implements Runnable { 
    private int cn; 

    public int getCN() {
      return cn;
    }

    ...
  }


  public class TaskExecutorExample { 
    MessagePrinterTask printerTask;

    public void printMessages() { 
      printerTask = new MessagePrinterTask();
      taskExecutor.execute(printerTask); 
    }
    ...
  }
