    import javax.swing.JOptionPane;
     
    public class History {
     
     
        public static void main(String[] args) 
        {
     
           //First Question: What is the capital of Mexico? 
            String[] question1 = {"Mexico City", "Paris"    //The choseable answers are made using String
                    ,"Washington D.C", "Tokyo"};
     
     
            String MexicoCapital = (String)JOptionPane.showInputDialog(null, "What is the capital of Mexico?:"
                    , "Question 1 of 10", JOptionPane.QUESTION_MESSAGE // question number is diplayed on top of text box
                    , null, question1, question1[0]); //Choices are called and displayed using joptionpane
     
     
            if (MexicoCapital == null)
            {
                JOptionPane.showMessageDialog(null, "You didn't pick a city!");
            }
            else
            {
     
                String funfact = "";
                switch (MexicoCapital)
                {
                    case "Mexico City":
                        funfact = "Correct";
                        break;
                    case "Paris":

    Anytime a block of code needs to be repeated, a loop can be the programming tool to accomplish that. I see you have the statement "Question 1 of 10" in your code which suggests to me the code is intended to ask 10 questions, and that sounds like a repeated activity - 10 times asking a question. That's where your loop goes, around the code that asks the question. Any of the loops, for, while, or do/while would work, but since you know the loop will run exactly 10 times, the for loop would be the typical choice.

    Something like:

    int questionNumber = 1;
     
    while ( questionNumber < 11 )
    {
        // ask question, get answer, etc.
     
        // increment the loop control variable so that it's not an infinite loop
        questionNumber++;
    }

                    , null, question1, question1[0]); //Choices are called and displayed using joptionpane
     
     
            if (MexicoCapital == null)

    Default Re: Is there anyway to use a Do While statement in this program?

    I'm guessing you don't yet know arrays, use of methods beyond the main() method, or use of helper classes. If you can't generalize the asking of questions and providing answers, then the purpose of a loop is not clear.

    Start over. If your program works now as it is, what are you trying to do? What is the requirement either as stated in the original assignment or resulting from instructor review, etc.? It would also be helpful to know what programming tools (like those I've mentioned above) you can, can't, or must use.

                }
    Your code really dirty, let make it more clearly & reusable instead.

    Example:

    Make a function to show UI
    void showQuestion(MyQuestion question)
    void showQuestion(String question, String[] option, string[] optionAnswer){
    //in this function, you will show question to user, for each option, you will have a optionAnswer to show the result to the user
    //Flow:
    // ShowQuestion(question)
    // ShowOption(option)
    // int selected = GetUserSelectedOption();
    // ShowResult(optionAnswer[selected])
    }
    well, all you need to do now is init your list of question, option, & optionAnswer, you could make a class to hold these data, like this
    classs MyQuestion{
    String question
    String[] option,
    String[] optionAnswer
    public MyQuestion(String,String[], String[]){}
    }
    ok, then you nit to init your list question:
    List<MyQuestion> questionCollection = new ArraayList<>();
    questionCollection.add(new MyQuestion("1 + 1 = ?",{"2","3","4"},{"yes, u right","no you wrong it's 2","no you need to learn it again"}));


    and then you go through your question and show it

    for(MyQuestion q : questionCollection){
    ShowQuestion(q);
    }
    ShowEndAndResult();

    OK ?
