jlabel干滚动文字?_J2SE

jlabel做滚动文字??
我想在jbuilder做的系统的欢迎窗口上的jlabel上做一个滚动文本，即＂欢迎光临＂这几个字在jlabel滚动显示，
请问谁有相关代码？或指点一下？？

------解决方案--------------------
用多线程吧。。

Java code

    class ScrollText extends Thread    {        String str = "        欢迎光临！";        public ScrollText()        {            this.start();        }                public void run()        {            str = str.substring(1,str.length())+str.charAt(0);            this.lable1.setText(str);//这是个内部内，这里的lable1就是你的那个lable        }    }
