change pictures every 2 sec

问题

I stack a bit so if anyone has any ideas it would be helpful. So currently the program is compiling and running but I do not know how to finish it. I am using eclipse. What i want to do is when i start the program to change 4 different pictures in every 2 seconds so if you have any advices do not be shy. Here is the program.

public class SlideShowGui extends JPanel implements ActionListener 
{
    JLabel name, comments, images;
    JTextField namejtf, commentsjtf, captionjtf;
    JButton submit;
    ImageIcon pictures, pictures2, pictures3, pictures4;
    boolean go = true;

    SlideShowGui()
    {
        name = new JLabel("Name:");
        this.add(name);

        namejtf = new JTextField(15);
        this.add(namejtf);

        comments = new JLabel("Comments:");
        this.add(comments);

        commentsjtf = new JTextField(15);
        this.add(commentsjtf);

        submit = new JButton("Submit");
        this.add(submit);
        submit.addActionListener(this);
        pictures = new ImageIcon("galileo1.jpg");
        images = new JLabel(pictures);

        pictures2 = new ImageIcon("galileo2.jpg");
        pictures3 = new ImageIcon("galileo3.jpg");

        this.add(images);

        captionjtf = new JTextField(24);
        this.add(captionjtf);

    }

    public void actionPerformed(ActionEvent ae)
    {

    }
}

回答1:

put Icon / ImageIcons to the Queue, Map, Array, List, Vector
by starting Swing Timer pick up Icon / ImageIcon from the array
add Icon / ImageIcons to the JLabel, by using JLabel#setIcon()
code related for Swing GUI should be initialized from invokeLater(), more in the Initial Threads
