copied!<p>I've changed your code so it should work as you intended. I'm not clear on what getEngineersUpdate() does, so I can't say for sure if it will work, but I've given you a start. I've included 2 options for how to handle it, with explanation in the comments. You can see how to use a Timer properly in the constructor, also. Finally, I don't have your full code, so I had to rig something together to simulate it.</p> <pre><code>class Marquee { public static void main(String[] args) throws InterruptedException { MyFrame frame = new MyFrame(); frame.setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE); frame.setVisible(true); frame.setAlwaysOnTop(true); frame.setBackground(Color.BLACK); frame.setResizable(true); } } class MyFrame extends JFrame { private String [] latestUpdate = new String[1]; private static final int DISPLAY_TIME = 3000; private Timer displayTimer; /* * Option #1: * Ideally, you'd have the thread that generates the "Engineers Update" messages call this * method. If you can't make this event based, then you should use option #2 */ public void newUpdate(String message) { setVisible(true); // change this to whatever you need to. text.setText(message); displayTimer.restart(); } // I used this to test it private JTextField text; public MyFrame() { // gets the maximum size of the screen Dimension d = Toolkit.getDefaultToolkit().getScreenSize(); //sets it to max. need to change this setSize(d.width, (d.height / 100) * 10); // this shit find the max size of screen and puts it bottom left GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment(); GraphicsDevice defaultScreen = ge.getDefaultScreenDevice(); Rectangle rect = defaultScreen.getDefaultConfiguration().getBounds(); int x = (int) rect.getMinX(); int y = (int) rect.getMaxY() - getHeight(); setLocation(x, y - 30); setTitle("ALERT::OUTAGE"); //MyPanel panel = new MyPanel(); //add(panel); text = new JTextField("Initial Text"); add(text); // this creates a timer that when it goes off, will hide the frame displayTimer = new Timer(DISPLAY_TIME, new ActionListener() { @Override public void actionPerformed(ActionEvent e) { setVisible(false); } }); // sets the timer not to repeat displayTimer.setRepeats(false); //This code is for option #2: updateTimer = new Timer(UPDATE_INTERVAL, new ActionListener() { @Override public void actionPerformed(ActionEvent e) { checkForNewUpdate(); } }); updateTimer.start(); } // This is for option #2 private static final int UPDATE_INTERVAL = 1000; private Timer updateTimer; /* * Option #2: * Not ideal, but this should work. */ public String[] checkForNewUpdate() { // I don't know how getEngineersUpdate() works // which would have made it much easier to help you. String tempUpdate = getEngineersUpdate(); // String comparison doesn't work like this in java. // you also had a sleeping NullPointerException here if (!tempUpdate.equals(latestUpdate[0])) { // this is when you have a new update, correct? newUpdate(tempUpdate); latestUpdate[0] = tempUpdate; } else if (tempUpdate.equals(latestUpdate[0])) { // it's the same update as last time, so do nothing } else if (tempUpdate.equals("NULL")) { // You need to handle this according to what getEngineersUpdate() does } return latestUpdate; } // This code is rigged to show how it would work private static int i = 0; private String getEngineersUpdate() { // 1 in 6 chance of returning "NULL" if (Math.random() * 6 - 1 < 0) return "NULL"; // probability of 1 in 4 of generating a new update if(Math.random() * 4 - 1 < 0) return "UPDATE #"+i++; else return "UPDATE #"+i; } } </code></pre>
