我想每隔一定時間更新對象屬性（調(diào)用休息服務）。我有對象定義和一個帶有new和set的類public class Obj {    private String data;    //Getters and setters}//A class with the new and sets:Public class setData{     public setData{        Obj o = new Obj();        o.setdata("hello");     }     TimerTask timerTask = new MyTimerTask();     Timer timer = new Timer(true);     timer.scheduleAtFixedRate(timerTask, 0, 10*1000);}public class MyTimerTask extends TimerTask {    @Override    public void run() {/*       Here is the question. How can I update the data property of        my object?       I need to call the rest service, and update. The data              string is on a        swing UI.       */    }}這是問題。如何更新對象的數(shù)據(jù)屬性？我需要致電其余服務，并進行更新。數(shù)據(jù)字符串在swing UI上。
