更新JProgressBar

java

我无法更新进度条…这是我的代码

Thread t=new Thread(new Runnable(){
        public void run(){
            int i=1;
            jProgBar.setMinimum(0);
            jProgBar.setMaximum(100);
            try {
                while(i<=100 || true){
                    jProgBar.setValue(i);
                    i++;
                    Thread.sleep(50);
                }
            }
            catch (InterruptedException ex){
                jProgBar.setValue(jProgBar.getMaximum());
            }
        }
    });
    t.start();

    .... Something code that correctly works

    t.interrupt();

进度栏状态仅在线程末尾更新。有人能帮我吗？？

谢谢大家我这样解决了

try{
       jProgBar.setIndeterminate(true);
       jProgBar.setStringPainted(true);
       jProgBar.setBorderPainted(true);
       new Thread(new Runnable() {
           public void run() {
               ...
               // here is code that i've to wait
               // after this i stop my jProgressBar
               ...
               jProgBar.setStringPainted(false);
               jProgBar.setBorderPainted(true);
               jProgBar.setIndeterminate(false);
       }
       }).start();
   }
   catch(IllegalStateException ex){
       //some code
   }
