How to print an array containing a string from another class?

advertisements

How would I go about printing an array that holds a string that is in another class using println? An example of what I mean is:

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?");

    }

}

In this other class, I want to grab a question from there like so:

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("");

    }

}


Return the QuestionArray from 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;

}

Then print like this:

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]);

 }

}
