Hi Yurij,

Of what I can make from your description you are more inclined towards creating a quiz kind of app, where the user can select one the answers for a given question. These answers are of different form element types for e.g. check boxes, drop down etc.

You can put question in one array and answers in another. use a global random variable and use it to call the question with their respective answers. For each answer you may select a different form element type.

If you can give a little more description of what exactly you aim for it would help.

Also you can check out this tutorial on creating a quiz app Code TutPlus . it uses string arrays to store answers, which could also be a good idea.

Thank You, it`s good answer. So, I will have 3 arrays:

```public String[] questions = {"1?", "2?", "3?"};

public String[][] variantsAnsvers;

variantsAnsvers[0][0] = "Bollean"; variantsAnsvers[0][1] = "";

variantsAnsvers[1][0] = "Checbox"; variantsAnsvers[0][1] = "variant 1, variant 2, variant 3, variant 4"; / how its done?

variantsAnsvers[1][0] = "Choose"; variantsAnsvers[0][1] = "variant 1, variant 2, variant 3, variant 4";

public String[] usersAnswers;```

And second problem what I see: How to change in design, at screen, buttons for diffrent types of answers?
