Ok, also mache ich ein Blackjack-Spiel für ein Projekt zum Jahresende in der Schule, aber wenn ich in einem Spiel "stehen" wollte, könnte der Code meine Eingabe nach dem Zufallsprinzip ignorieren und dann aufhören, zusammen zu arbeiten. Kann das jemand herausfinden? weder ich noch mein Lehrer konnten es. (Es tut mir leid, es gibt so viel Code, ich weiß nicht, ob Sie alle Klassen müssen mir helfen)Ich habe einen Fehler, der zufällig passiert, wenn ich einen Int eingegeben habe, weiß jemand, was los ist?

Mein Problem scheint mit der Wahl() -Methode in der Spielklasse. Hin und wieder, wenn es aufgerufen wird, ignoriert es meine Eingaben und sieht so aus, als ob es in eine Endlosschleife geht, aber wenn ich in einen Debugger schaue, zeigt es nur, dass der Scanner meine Eingabe ignoriert.
Noch einmal, es tut mir leid, es gibt so viel Code, aber niemand kann das herausfinden und ich fragte mich, ob jemand helfen kann.
