I need to execute/display a series of events from a Arraylist to a JTextArea, however, each Event gets execute with different time. Following is the code, it fails while at second Event in the loop:

```
   Thread worker = new Thread(new Runnable()
            {
                public void run()
                {
                    while (eventList.size() > 0)
                        for (Event ev : eventList)
                        if(ev.ready())
                        {
                            /*try
                            {
                                Thread.sleep(1000);
                            } catch (InterruptedException e1)
                            {
                                e1.printStackTrace();
                            }*/
                            jTextArea.append(ev.toString() + "\n");
                            eventList.remove(ev);

                        }
                }
            });
            worker.start();

```
