You can test the MarqueThread
class with the following program:
import javax.swing.*; public class ThreadTestor { public static void main (String argv []) { JFrame frame = new JFrame("Thread Test"); Marquee marquee = new Marquee("Buy On To Java Today!"); MarqueeThread thread = new MarqueeThread(marquee); thread.start(); frame.getContentPane().add("Center", marquee); frame.setSize(550, 200); frame.addWindowListener(new ApplicationClosingWindowListener()); frame.show(); } }
