[thesingh]

Hi there,

New to java but i have to jump into the deep end of things...

I have created an arraylist that stores answers for questions and answers for a quiz im doing.

public ArrayList storeAnswer3 ()
{
ans3.add("1995");
ans3.add("1996");//answer
ans3.add("1997");
ans3.add("1998");

return ans3;
}

What i need to do is declear that "1996" is the right answer. I been trying to look into get methods but to no success.

Can somebody help me???

How do you plan on using it? I still don't get your question.

So basically you have a list of answers and one of them is the correct answer.
Simply build a little class for it:

public class Answers {
   private List<String> answers;
   private int correct;
 
   public Answers(List<String> answers, int correct) {
      this.answers= answers;
      this.correct= correct;
   }
 
   public List<String> getAnswers() { return answers; }
   public String getCorrectAnswer() { return answers.get(correct); }
   public int getCorrectIndex() { return correct; }
}

I'm sure you can figure out the details by yourself.

kind regards,

sorry....

Ok this is what i need...

I need to declare what the right answer is so when you click on the right answer in the interface it will show a pop up message saying " thats right".

I have a interface class and in that i have these codes


private JLabel xField = new JLabel();
private JButton yField = new JButton();
private JButton zField = new JButton();
private JButton aField = new JButton();
private JButton bField = new JButton();
{
ans = q.storeQuestion();
ans1 = q.storeAnswer();

cat1 = ans.get(0);
xField.setText(cat1.get(0));
yField.setText(ans1.get(0));
zField.setText(ans1.get(1));
aField.setText(ans1.get(2));
bField.setText(ans1.get(3));
}

these are label and buttons which are showing the strings of the questions and answers which are located in another class...

What i need to do is define what the right answer is so when you click on that button it will come up with a message...

Is that any clearer???

Yep, sure; never be afraid to craft a new class or interface instead of knitting
more and more stuff to an already existing class. It'll keep your code base clean.

Thanks alot jos...

Thanks alot jos...

You're welcome of course. Another tip: if you really want to play it safe you
can store a Collections.unmodifiableList() so noone will be able to change your
answers list from this proposed class.

kind regards,
