java - 如何打印包含另一个类的字符串的数组？

我将如何使用println打印一个包含另一个类中的字符串的数组？我的意思是一个例子：

public class questions{

    public void QuestionDatabase(){

        String[] QuestionArray;
        QuestionArray = new String[2];

        QuestionArray[0] = ("What is a dog?");
        QuestionArray[1] = ("How many types of dogs are there?");

    }

}

在这另一堂课中，我想像这样从那里抓住一个问题：

public class quiz{

    public static void main (String[] args){

       //Here is where I want to grab QuestionArray[0] and print to the screen.
        System.out.println("");

    }

}

最佳答案

从QuestionArray返回QuestionDatabase()：

public String[] QuestionDatabase(){

    String[] QuestionArray;
    QuestionArray = new String[2];

    QuestionArray[0] = ("What is a dog?");
    QuestionArray[1] = ("How many types of dogs are there?");

    return QuestionArray;

}

然后像这样打印：

public class quiz{

public static void main (String[] args){

   //Here is where I want to grab QuestionArray[0] and print to the screen.
    System.out.println(new questions().QuestionDatabase()[0]);

 }

}
