java PinAutomaat

[Verwijderd]

Heey tweakers, ik ben voor school bezig met het programmeren van een PIN automaat maar het wil niet helemaal lukken. Het word geprogrammeerd in JAVA en en ben hier nieuw mee (uberhaupt met het programmeren). Ik kan geen fouten ontdekken maar toch werkt het niet, als ik het project (gebruik NetBeans laatste versie) wil runnen dan verloopt het wel succesvol maar toch krijg ik geen beeld, ookal zou dat wel zo moeten zijn? Hier onder volgt het dan:

Dit is het "Grafische" gedeelte:

g.drawString(boodschap,x,y);
}

public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {

public void run() {
new ATM().setVisible(true);
}
});
}


}

sorry voor de nogal onduidelijke taal mss, maar in Netbeans is het overzichtelijker

als iemand een fout kan ontdekken zou het fijn zijn, ik kom er niet uit. Heb ook al geprobeerd het gewoon in de command promt te runnen, maar dat werkt ook niet.

[DutchCommando]

Java:

private static final int MAX_BOODSCHAP_LENGTH = 4;

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
   AppendBoodschap("1");
}

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
   AppendBoodschap("2");
}

private void AppendBoodschap(String boodschapAppend)
{
   Beeldscherm scherm = (Beeldscherm)jPanel1;

   if (scherm.boodschap.length() < MAX_BOODSCHAP_LENGTH) 
   {
      scherm.boodschap += boodschapAppend;
      jPanel1.repaint(); 
   }
}

Maar hier ligt het ongetwijfeld niet aan. Geen zin om al die code door te spitten.

[RobIII]

Als je code post, post dan enkel relevante code; dit soort enorme lappen heeft niemand zin in om door te gaan spitten. Daarbij is het niet (allemaal) relevant voor je probleem. Als je code post, gebruik dan code tags en neem even onze Programming Beleid Quickstart door voordat je en nieuw topic opent want we zien graag wat je zelf al hebt geprobeerd, wat er niet werkt en waarom je denkt dat dat zo is. "Ik kan geen fouten ontdekken maar toch werkt het niet" is natuurlijk nogal behoorlijk vaag; met wat debuggen moet je al een heel eind kunnen komen.
