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 :
- import java.util.Observable;
- import java.util.Observer;
- import processing.core.PApplet;
- public class InterfaceOutAndroid extends PApplet implements Observer {
- private static final long serialVersionUID = 6020713207736311342L;
- Grille laGrille;
- int[] couleurs = {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)};
- public InterfaceOutAndroid(Grille grille) {
- laGrille = grille;
- }
- @Override
- public void update(Observable arg0, Object arg1) {
- laGrille = (Grille) arg0;
- }
- public void setup() {
- size(200,360);
- Jeu leJeu = new Jeu();
- leJeu.initialiserInterfaceOutAndroid();
- leJeu.initialiserInterfaceInClavier();
- ObservateurJeu o = new ObservateurJeu(leJeu);
- KeyboardListener2 kl = new KeyboardListener2();
- MyTimer t = new MyTimer();
- t.setPasDeTemps(800);
- kl.addObserver(o);
- t.addObserver(o);
- new Thread(t).start();
- new Thread(kl).start();
- PApplet.main(new String[] {"--present","InterfaceOutAndroid"});
- }
- public void draw() {
- for (int i = 0; i < laGrille.getLargeur(); i++) {
- for (int j = 0; j < laGrille.getHauteur(); j++) {
- fill(couleurs[laGrille.getCase(i,j).getCouleur()]);
- stroke(255);
- rect(i*20, j*20, 20, 20);
- }
- }
- }
- }
I don't understand what's wrong.
I did the following small test and it worked without any problem:
- import processing.core.PApplet;
- public class Main extends PApplet {
- private static final long serialVersionUID = 4648172894076113183L;
- public void setup() {
- size(200,360);
- for (int i=0;i<10;i++){
- for (int j=0;j<18;j++){
- alea = floor(random(couleurs.length));
- fill(couleurs[alea]);
- stroke(255);
- rect(i*20,j*20,20,20);
- }
- }
- }
- 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)};
- private int alea;
- public void draw() {
- }
- }
Could the issue come from the Observer pattern?
Thanks a lot for your help !
