draw image in applet

Question

i having problem with draw image in applet. i want to display all images one by one in applet but it shows only last image of the folder my code is given below.

public class ImageInSwingTest extends JApplet
{
    String filePath="C:\\Users\\yogi\\Pictures\\pictures"; //all .png files more than 200 files
    String files;
    File folder=new File(filePath);
    File[] listOfFiles;
    Image m;

    @Override
    public void init()
    {
        listOfFiles=folder.listFiles();
        for(int i=0;i<listOfFiles.length;i++)
        {
            if(listOfFiles[i].isFile())
            {
                files=listOfFiles[i].getName();
                if(files.endsWith(".png"))
                {
                    String filepath=listOfFiles[i].getAbsolutePath();
                    System.out.println(filepath);
                    try {
                         m = ImageIO.read(new File(filepath));
                        paint(ImageInSwingTest.this.getGraphics());

                    } catch (IOException ex) {
                        Logger.getLogger(ImageInSwingTest.class.getName()).log(Level.SEVERE, null, ex);
                    }
                }
            }

        }
    }
    public void paint(Graphics g)
    {
        g.drawImage(m, 0, 0, this);

    }

}

so, please can any one tell me how can i display all images one by one.? Thanks.

`String filePath="C:\\Users\\yogi\\Pictures\\pictures";` This will not work for your images on the server, even in a trusted applet. It will be necessary for either the server to supply a file list on demand, or for the file names to be defined as parameters in the applet element. — Andrew Thompson, May 24 '12 at 09:04

because each of loop inside for(int i=0;i<listOfFiles.length;i++) replacing JApplet's contents
put JPanel to the JApplet
put Images to the array of Icon[]
put Icon to the JLabel
use GridLayout for placing JLabel with Icons to the JPanel
don't paint to the JApplet directly, use JPanel or JComponent with override method paintComponent() instead of paint()

EDIT

actually i want all images to replace each other so all images are look like playing movie

you have to pause this process by Thread.sleep(int);
you can use Thread.sleep(int); inside SwingWorker or Runnable#Thread,
don't use Thread.sleep(int); other ways in the Swing GUI, because to block Event Dispatch Thread, and is possible that nothing will be painted or only the last image too
Runnable#Thread would be better and easiest, but any output from Runnable#Thread to the Swing GUI you have to wrap JLabel.setIcon(myIcon) to the invokeLater

Also consider using a [*Swing Timer*](http://docs.oracle.com/javase/tutorial/uiswing/misc/timer.html). – trashgod May 23 '12 at 10:13

The time taken to end the loop is so short you can only see the last image displayed. Try adding a pause after drawing each image.
