随机测验有一个答案

Question

你可以帮我解决android studio中测验随机问题的代码吗？我知道随机的代码，但问题是我也有答案，我不知道如何连接它。这是我的代码：

public class Questions {



public String mQuestions[]= {
        "Care este prima planeta?",
        "Cine a fost primul presedinte al SUA?",
        "In ce an a murit Adolf Hitler?",
        "De cate ori a iesit Michael Schumacher campion mondial al F1?",
        "La ce echipa a jucat Gica Popescu in Spania?"



};

private String mChoices[][]={
        {"Mercur","Venus","Pamant","Marte"},
        {"Abraham Lincoln","William H. Taft","George Washington","John F. Kennedy"},
        {"1940","1945","1944","1947"},
        {"3","2","4","7"},
        {"Barcelona","Real Madrid","Valencia","Espanyol"}


};
private String mCorrectAnswers[]={"Mercur","George Washington","1945","7","Barcelona"};

public String getQuestion(int a){
    String question = mQuestions[a];
    return question;
}

public String getChoice1(int a){
    String choice= mChoices [a][0];
    return choice;
}
public String getChoice2(int a){
    String choice= mChoices [a][1];
    return choice;
}
public String getChoice3(int a){
    String choice= mChoices [a][2];
    return choice;
}
public String getChoice4(int a){
    String choice= mChoices [a][3];
    return choice;
}
public String getCorrectAnswer(int a){
    String answer=mCorrectAnswers[a];
    return answer;
}

}

Answer 1

为什么不使用类或结构这样的问题：

class Question
{
  String   Question;
  String[] Choices;
  int      CorrectChoiceIndex;
}

这样，所有相关数据都存储在一起，所以如果你创建一个问题数组，你只需选择一个有效的随机索引。
