java - Android 中的类就像 Swift 中的 Struct

Question

在我的 swift 应用程序中，我有这段代码:

struct Question
{
    var QuestionLbl : String!
    var Answers : [String]!
    var Answer : Int!
}

之后我像这样使用这个结构

var Questions = [Question]()

Questions =
            [Question(QuestionLbl: "Whats my name?", Answers: ["John","Josh","Adam","Leo"], Answer: 0),

                Question(QuestionLbl: "Whats my moms name?", Answers: ["Jessica","Crystal","Samanta","Kate"], Answer: 3),

                Question(QuestionLbl: "Whats my fathers name?", Answers: ["Ed","Blake","Jeff","Jonhson"], Answer: 2)]

现在，我正在尝试为 Android 制作相同的应用程序..所以我创建了一个类并尝试做同样的事情......这是类文件:

public class Question {
    String questionLabel;
    String[] answersOptions;
    Integer correctAnswer;

    public Question(String questionLabel, String[] answersOptions, Integer correctAnswer) {
        this.questionLabel = questionLabel;
        this.answersOptions = answersOptions;
        this.correctAnswer = correctAnswer;
    }

    public String getquestionLabel() {
        return questionLabel;
    }

    public String[] getanswersOptions() {
        return answersOptions;
    }

    public Integer getcorrectAnswer() {
        return correctAnswer;
    }
}

这就是我在主要 Activity 中尝试做的事情:

Question[] questions;
        questions = {
                 Question("Whats my name?",{"John","Josh","Adam","Leo"}, 1),
                 Question("Whats my mom's name?",{"Jessica","Crystal","Samanta","Kate"}, 1)
        };

但是没有用。有什么问题吗？

看this发布声明数组的语法。本质上，它看起来像:

questions = new Question[]{
    new Question("What's my name?", new String[]{"John","Josh","Adam","Leo"}, 1),
    new Question("What's my mom's name?", new String[]{"Jessica","Crystal","Samanta","Kate"}, 1)
    //etc..
}
