I am currently trying to add a GUI to a program I had made. Currently, I am going a bit different with getting the data, as before I had the user implement all the required input. Now I am trying to make it to allow the user to select the xp required rather than inputting it themselves.

So because of this I am having quite the amount of issues. So my question is, how can I go about reading integers from a file, from those integers creating an array, then after putting them in an array, putting them all into a combobox for selection by the user?

If needed I will post the code I have currently been fiddling with to try to get it work. However, if I could get a generic code that I could use for this, I'm sure I'd be able to make it work in the program.

Something like this? [ Register or Signin to view external links. ] (excluding combobox)

Perhaps I should have said that I mainly needed help with taking an array of type int to show all of its elements in the comboxbox lol. I was able to easily figure out how to take an int and put it into an array, just having trouble with the comboxbox reading from the array.

Keep getting errors with that part.

This is what I was currently attempting to do:
Scanner reader = new Scanner(new File("levels.txt"));
         ArrayList<Integer> exprequired = new ArrayList<Integer>();
         while (reader.hasNext()){
            exprequired.add(reader.nextInt());
            reader.nextLine();
        reader.close();
         }
      JComboBox<Integer> reqexp = new JComboBox<>(exprequired);


However, that just keeps giving me an error on the JComboBox of "cannot infer type arguments for JComboBox<>"

Read the Javadoc for JComboBox [ Register or Signin to view external links. ]

Look at the constructor summary. None of them take a List as their input. There is one for just an array though. You're currently working with ArrayLists - not arrays. You have to convert your ArrayList to an array.

Thanks, that completely makes sense now, lol. Hopefully I can finish this program now.
