Erstellen Sie einen Multiple -Choice -Test mit Windowbuilder (Java) ⇐ Java

[Anonymous]

Ich erstelle einen Multiple -Choice -Test mit Windowbuilder für einen Schulauftrag. Ich bin fast fertig, aber ich habe Probleme, die Punktzahl zu halten. Die Punktzahl scheint sich nicht zu summieren. Ich verwende zwei Klassen, um den Multiple -Choice -Test zu erstellen. Wenn mir jemand helfen kann, das Score -System einzurichten, das sehr geschätzt wird.
