java set delay to change imageicon

Question

i\'m trying to set a delay when a button is pressed to set an imageicon to a certain image then set another delay so that another image would be set, all of this by single click

Answer 1

You should try executing the code that sets the image in the event dispatch thread using InvokeLater.

SwingUtilities.invokeLater(new Runnable() {
    public void run() {
        lblNewLabel.setIcon(and);
    }
});

sleeep();

SwingUtilities.invokeLater(new Runnable() {
    public void run() {
        lblNewLabel.setIcon(and);
    }
});
