InstantiationException & Applet not initialized

Hi everyone,

I'm new to processing (and Java). I'm trying to make a Tetris game using Processing but the Processing part won't work.

I get the following error :

java.lang.InstantiationException: InterfaceOutAndroid

at java.lang.Class.newInstance0(Unknown Source)

at java.lang.Class.newInstance(Unknown Source)

at sun.applet.AppletPanel.createApplet(Unknown Source)

at sun.applet.AppletPanel.runLoader(Unknown Source)

at sun.applet.AppletPanel.run(Unknown Source)

at java.lang.Thread.run(Unknown Source)

charger : InterfaceOutAndroid.class cannot be instantiated.

I'm using Eclipse. Here is my class :
2. import java.util.Observable;
3. import java.util.Observer;
5. import processing.core.PApplet;
7. public class InterfaceOutAndroid extends PApplet implements Observer {
9. private static final long serialVersionUID = 6020713207736311342L;
11. Grille laGrille;
12. int[] couleurs = {color(255,0,0),color(0,255,0),color(0,0,255),color(255,255,0),
13. color(255,140,0),color(162,0,255),color(0,208,239)};
15. public InterfaceOutAndroid(Grille grille) {
17. laGrille = grille;
18. }
20. @Override
21. public void update(Observable arg0, Object arg1) {
23. laGrille = (Grille) arg0;
25. }
27. public void setup() {
29. size(200,360);
31. Jeu leJeu = new Jeu();
33. leJeu.initialiserInterfaceOutAndroid();
34. leJeu.initialiserInterfaceInClavier();
36. ObservateurJeu o = new ObservateurJeu(leJeu);
37. KeyboardListener2 kl = new KeyboardListener2();
39. MyTimer t = new MyTimer();
40. t.setPasDeTemps(800);
42. kl.addObserver(o);
43. t.addObserver(o);
44. new Thread(t).start();
45. new Thread(kl).start();
47. PApplet.main(new String[] {"--present","InterfaceOutAndroid"});
49. }
51. public void draw() {
53. for (int i = 0; i < laGrille.getLargeur(); i++) {
55. for (int j = 0; j < laGrille.getHauteur(); j++) {
57. fill(couleurs[laGrille.getCase(i,j).getCouleur()]);
58. stroke(255);
59. rect(i*20, j*20, 20, 20);
61. }
62. }
64. }
66. }
I don't understand what's wrong.

I did the following small test and it worked without any problem:
2. import processing.core.PApplet;
4. public class Main extends PApplet {
6. private static final long serialVersionUID = 4648172894076113183L;
8. public void setup() {
9. size(200,360);
10. for (int i=0;i<10;i++){
11. for (int j=0;j<18;j++){
12. alea = floor(random(couleurs.length));
13. fill(couleurs[alea]);
14. stroke(255);
15. rect(i*20,j*20,20,20);
16. }
17. }
18. }
20. int[] couleurs={color(0,0,0),color(255,0,0),color(0,255,0),color(0,0,255),color(255,255,0),color(255,140,0),color(162,0,255),color(0,208,239)};
21. private int alea;
23. public void draw() {
27. }
29. }
Could the issue come from the Observer pattern?

Thanks a lot for your help !
