De laatse bestaat niet: Java arrays beginnen bij index 0.

Zou ik gewoon
int res[] = poging(doepoging);
van maken.

Niet gebruikt of is je echte code iets als:
JTextField kleur [] = new JTextField[4];
> public void actionPerformed(ActionEvent actionEvent)
> {
> String commando = actionEvent.getActionCommand();
> if (commando.equals("Doe een poging"))

for(int i = 0; i<4; i++) {
try {
doepoging[i] = Integer.parseInt(kleur[i].getText());
} catch(NumberFormatException e) {
System.out.println("Kleurnummer " + i + " is geen nummer!");
doepoging[i] = 0; // of doe iets anders
}
}
int res[] = poging(doepoging);
