acual and formal arguments differ in length?

@Ok - I actually already tried that, and it still doesn't work.

@ TheBig - I already found that website, and I tried to use their example, but it didn't work either. :/

@ TheBig - The problem is, those are old documentations, and they don't work with Java 7 (I upgraded). I couldn't find the Java 7 docs. :/ I acually found a way to do it (the array probably isn't necessary, but i'm new to arrays, so I'm trying to use them as much as I can to see how they work.) :

Object[] options = {"X, please!",

"O, please!"};

int startChoice = JOptionPane.showOptionDialog(null,

"Who do you want to go first?",

"Starter?",

JOptionPane.YES_NO_CANCEL_OPTION,

JOptionPane.QUESTION_MESSAGE,

null,

options,

options[1]);
