Sınav programım için JTabbedPane kullanıyorum, cevaplarımı görüntülemek için düğmelerimi nasıl alacağımı bilmiyorum

Question

Dediğim gibi, her bölmedeki soruyu görüntüleyebilmek için dizinin içinden nasıl geçeceğimi bilmiyorum. 8 bölüme sahip ve her biri bir soru içermeli, bir tane için çalışmayı başarabildim (soru 1 dizideki ilk girişi gösterir) ama diğerleri değil.

Herhangi bir öneriniz var mı?

sorunlarla listenizde (probList) dayalı her sekmeyi kuracağına CreateTabs adlı bir yöntem oluşturabilir İşleri kolaylaştırmak için. Eğer böyle bir şey olurdu QuizEasy Yapıcıda

public void CreateTabs() { 
    JPanel question = null; 
    JLabel lbQuestion = null; 
    JButton ansA = null; 
    JButton ansB = null; 
    JButton ansC = null; 
    for (int i=0;i<probList.length;i++) { 
     question = new JPanel(); 
     lbQuestion = new JLabel(probList[i].getQuestion()); 
     question.add(lbQuestion); 
     ansA = new JButton(probList[i].getAnsA()); 
     ansB = new JButton(probList[i].getAnsB()); 
     ansC = new JButton(probList[i].getAnsC()); 
     question.add(ansA); 
     question.add(ansB); 
     question.add(ansC); 
     quiz.addTab("Question " + (i+1), question); 
    } 
} 

: Aşağıdaki kod bakın

public QuizEasy() { 
    problems(); 
    CreateTabs(); 
    ... 
}
