Question

Hi I have 2 list defined:

ArrayList<JLabel> questionsList = new ArrayList<JLabel>();
ArrayList<JRadioButton> answersList = new ArrayList<JRadioButton>();

I try to read questions and answers in format like that:

1st Question 
  answer1
  answer2

2nd Question 
  answer1
  answer2
etc.

So 1st question is read from list questionsList then I want to read from another list answersList all answers to that question and etc.

In questionsList I read data from mysql and they are saved in JLabels in format like:
1. Question one
2. Question two
etc

In answersList I read data from mysql and they are saved in JRadioButtons in format like:
answer1

answer2
etc

My code so far:

    int height = 0;

        for(int i1 =0; i1<questionsList.size(); i1++)
        {   
              client.insideFillPollPanel.add(questionsList.get(i1)).setBounds(20, 20+150*i1, 480, 14);

            height = 20+150*i1;  

            for(int i2 =0; i2<answersList.size(); i2++)
            client.insideFillPollPanel.add(answersList.get(i2)).setBounds(20, 50+30*i2, 480, 14);



        }

How do i solve it to be display like 1st format I showed so question then asnwers question and asnwers?

Answer 1

I would recommend you to create a Question class which contains both the question and all answers belonging to that question and then, instead of having

ArrayList<JLabel> questionsList = new ArrayList<JLabel>();
ArrayList<JRadioButton> answersList = new ArrayList<JRadioButton>();

You use

ArrayList<Question> questions = new ArrayList<Question>();

(as a side note: It is considered good practice to program against interfaces, so instead of storing the questions in a ArrayList<Question> I suggest you go for a List<Question>.)

---

For example:

class Question {

    JLabel questionLabel;
    List<JRadioButton> answers;

    public Question(String q, String... ans) {
        ...
    }
}
