How to create running text with jlabel?

Let's just say i have a jlabel with a text in it. And i want the text keep changing every second to the left just like running text on the billboard.

Is it possible? if yes, how?

You should use javax.swing.Timer to schedule JLabel updates. Please, see simplified code snippet below:

JFrame frame = new JFrame("Test");
frame.setSize(300, 300);
JLabel label = new JLabel("This is text!!!");
frame.add(label);
frame.setVisible(true);

final int labelWidth = 300;
final AtomicInteger labelPadding = new AtomicInteger();
Timer timer = new Timer(20, new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent e) {
        label.setBorder(new EmptyBorder(0, labelPadding.getAndIncrement() % labelWidth, 0, 0));
    }
});
timer.start();

Note that AtomicInteger is not necessary, but you need some final holder to be able to use it inside inner class or lambda.
