Afficher deux images

Bonjour, je souhaiterai alterner toutes les secondes, deux images. Ceci dans un panel. C'est à dire, afficher une image, attendre une seconde puis afficher la seconde, réafficher la 1ère, etc.

Comment puis-je faire? sachant que je suis débutant.

Merci d'avance.

Voici une solution en utilisant un JLabel dans ton JPanel.

public class PanneauImage extends JPanel {
	private static final String IMAGES[] = { "image1.jpg", "image2.jpg" };
	private JLabel label = new JLabel();
	private static final Icon ICONE1 = new ImageIcon(IMAGES[0]);
	private static final Icon ICONE2 = new ImageIcon(IMAGES[1]);
	private static final Icon ICONES[] = { ICONE1, ICONE2 };
	private int compteur = 0;
	private Timer timer;
 
	public PanneauImage() {
		super();
		compteur = 0;
		label.setIcon(ICONES[compteur]);
		add(label);
 
		// Création et lancement du timer
		timer = new Timer();
		timer.schedule(new Action(this), 0, 1 * 1000);
	}
 
	class Action extends TimerTask {
		PanneauImage panel;
 
		public Action(PanneauImage panel) {
			this.panel = panel;
		}
 
		public void run() {
			compteur = (compteur+1) % 2;
			panel.getLabel().setIcon(ICONES[compteur]);
		}
	}
 
	/**
         * @return the label
         */
	public JLabel getLabel() {
		return label;
	}
}

comment faire appel à la classe PanneauImage depuis ma classe Alarme ?
