How to store the data of a file into an ArrayList?

Question

Hi! everyone.
I want to know
if I have a File, and the data in the file are type int, type String...
And I have a ArrayList which is of type Question
How do I store the data of that file into the ArrayList
I tried to use the while loop(use the hasNextLine() to read the data line by line)
But I cannot add data which are not of type Question to the ArrayList.
Can you tell me what I should do, please?
I also wonder that
The data of the file are of many types, but when I try to read it with the nextLine(), the data all turn out to be of type String. Why?
Thank you.

No, a line in the file is just part of a question
The format of the file is like this:
*<question type code>                    :     String*
*<question point value>                    :     int*
*<question category>                         :     String*
*<question difficulty level>               :     int*
*<question text>                              :     String*
*<question correct answer>               :     String*
*<optional question-specific data>     :     String*
*<question terminator>                    :     String*
And here is an example
TF //TrueFalseQuestion
5 //points value
None //category
3 //difficulty level
The capital of the United States is Washington, D.C. //question text
True // answer
*** //quetion terminator
I created an ArrayList in the Test class:
private ArrayList<Question> questions; // Create inside constructor
    public Test (String name, String instr)
        testName = name;
        scoreEarned = 0;
        scorePossible = 0;
        instructions = instr;
        questions = new ArrayList<Question>(); //[MAX_NUMBER_OF_QUESTIONS];
    }And I tried to use the following method to store the data of the file to the ArrayList
// This method loads a set of questions from a plain text file
    public void loadQuestionsFromFile(String fileName) throws FileNotFoundException
        try
            File fileReader = new File("input.txt");
            Scanner sc = new Scanner(fileReader);
            while (sc.hasNextLine())
                // I don't know how to pass the data I got from the nextLine() method to the ArrayList because they are of different type
        catch (FileNotFoundException a)
            System.out.println(a);
    }    As all you said, I should create an Question object in the while loop
Question temp = new Question ();But I have no idea how to pass the int and String to the Question object.
Thank you
