Hallo !
Ich bin neu hier in diesem Forum und habe eine Frage: Warum bekomme ich hier eine ConcurrentModificationException ?
[code=Java]for(Spiel aSpiel : aktuelleSpiele) //<------ Hier: ConcurrentModificationException
{
int a = 0;
try
{
int tipp1 = Integer.parseInt(tipps.get(a).getText()); //Tipp1 bekommen
a ++;
int tipp2 = Integer.parseInt(tipps.get(a).getText()); //Tipp2 bekommen
a ++;
aktuellerSpieler.addTipp(new Tipp(tipp1, tipp2, aSpiel)); //Neuen Tipp fuer aktuellen Spieler setzen
}
catch(NumberFormatException ex)
{
JLabel err = new JLabel("Bitte gueltige ganze Zahlen eingeben !");
panel2.add(err);
frame.add(panel2);
frame.setVisible(true);
}
}[/code]
Es geht um ein TippSpiel-Programm und die Exception kommt in der markierten Zeile.
Falls ihr zu Beantwortung der Frage das hier braucht:
