Im having trouble with 2.6 the array

Listing 2.6 Adding variables and a Question array (

I’m having trouble with the following line of code:

//adding question array
private Question[] mQuestionBank = new Question[]{
 new Question(R.string.question_australia, true),
 new Question(R.string.question_oceans, true),
 new Question(R.string.question_mideast, false),
 new Question(R.string.question_africa, false),
 new Question(R.string.question_americas, true),
 new Question(R.string.question_asia, true),
 }; //end of question array*************
private int mCurrentIndex = 0; // index for array

The code provided looks fine.

What’s your trouble?
Please also provide file strings.xml under directory /res/values.

Im getting error that Question isn’t recognized. The Question [ ] isn’t recognized.

I will also show you my string files

Please also show your file

    private int mTextResId;
    private boolean mAnswerTrue;

public class Question(int textResId, boolean answerTrue)
mTextResId = textResId;
mAnswerTrue = answerTrue;

public int getTextResId()
        return mTextResId;

public void setTextResId(int textResId)
        mTextResId = textResId;

public boolean isAnswerTrue()
        return mAnswerTrue;

public void setAnswerTrue(boolean answerTrue)
        mAnswerTrue = answerTrue;


public class Question(int textResId, boolean answerTrue)  // this line is also incorrect
mTextResId = textResId;
mAnswerTrue = answerTrue;
}               //  <- I guess you lost the right brace here. Please check whether you have some compile error in file

Let me paste the correct one here.

public class Question {     // class name without any parameter

    private int mTextResId;
    private boolean mAnswerTrue;

    public Question(int textResId, boolean answerTrue) {    // constructor
        mTextResId = textResId;
        mAnswerTrue = answerTrue;
    }                                       // constructor with right brace

    // ......

Thank you Crystal. I’ll give it a go and let you know the results.

I just wanted you to know its working perfectly. Thank you. I was able to find other smaller errors because of that 1 error.

My problem is not with the class Question but with the java array Question[]. Everything works correctly until I add a 2nd string to the array. In particular I get the error 'cannot resolve symbol question_oceans". I have checked many times and my code is identical with the text. Help will be greatly appreciated.

Hi. I’m new here. You should post what you have so you can have a second set of eyes. I remember posting this problem but my code was incorrect and Crystal showed me my error.

My array problem had a simple solution. I was able to figure out the trouble was probably the file. While searching on Google, there was a suggestion to rebuild. When I did that the file was updated to give id numbers to the new array items I had added to the code. Then everything worked correctly.

Ok I’m glad you rolling.

I think you should get some time to learn core java, and after that come back to android/ Good luck!

Good Luck to you too.
