TXT files, DB., ECT. also the PC that will run this will not have access to any network connection (theatrically) and can be stored in side of the .jar file. any good source you know that will be good to look at please post them and your opinions also.

    A text file would be the simplest and could easily be included in a jar file.

    What's the easiest to program and the easiest to make changes to? I'd say put it all in one file.

    Norm has a great idea and with good reasoning.
    I come from the other side of the fence on this however.
    I would suggest taking the object oriented approach, and maintain a separate file for each question.
    Within that file I would probably place the question itself on the first line,
    the correct answer on the second line,
    a series of seemingly correct answers on the next several lines,
    a delimiter on the next line,
    and a series of comical, obviously wrong answers on the next few lines.

    Then I would program it to select questions from the possible (available) files, be sure to include the correct answer, and on occasion a comical answer. (I assume there will be some choices anyway, not much said about what your game is)

    Could having separate files for each question be a maintenance problem?
    How do you add more questions? How does the program find all the files it needs to read?
    It can be done, but its more complicated than having it all in one file. Perhaps an index file that lists all the question files? Again a maintenance problem.

    Not that I can forsee given the OP's OP. No need to modify during runtime, just read. No troubles there. Any time they are modified, the new jar will be distributed with the mods, so far so good.

    Drop a new txt file in the questions folder.

    Read the file names in the questions folder.

    I agree your idea is good, just different than my approach.

    I do not see this extra file as a necessary step, and therefore not a maintenance problem.

    Read the file names in the questions folder.
    Is that a bit harder in a jar file? No File class to do the work.

    Separate files can be done, just a lot more work.

    I will admit it is different, but please explain how it is harder. What is it I do not see? Reading the file names do you mean?

    How is reading an all in one file allowed to use a class you can not use by multiple files? Or have I misunderstood the statement?

    I can agree it is 'some' more work. But I can not go with a lot more. Plus I say the flexibility and ease of maintenance stands tall enough to outweigh more code to get the file names vs less code filtering the all in one file to be read. But truthfully in the end that would depend on the specifics. Maybe each question only needs one answer, in which case I would go with the all in one file. But the impression I get from the OP is that there are multiple answers for the questions. In which case I disagree with the all in one.

    Flexibility/Maintenance:
    Adding questions/answers is as easy as adding a file to the folder.
    Removing questions/answers is as easy as removing a file from the folder.
    Modifying questions/answers is as easy as replacing a file in a folder.
    Each question can have a different pool of wrong answers with a different number of answers in it's pool.

    I agree it can be done either way, I just do not see the advantage to an all in one file besides the extra work to read file names associated with the multiple file approach.

    I've forgotten the coding used to read the contents of a folder in a jar file. For a disk folder, the File class's list() method does it.

    Your approche sounds nice, also I'm making this for a compintition, and will latter realse this to teachers for their class room reviews as free were. How wood a jTable to create and manage all the files / edit the files work?

    Also this may make a sticky Becous it can benefit outher programers also.

    here is a explanation i found for this.
    java - How do I access the content of folders inside a jar file? - Stack Overflow

    import java.util.*;
    import java.net.*;
    import java.util.jar.*;
    class I18n {
        public static void main( String ... args ) {
            getLocaleListFromJar();
        }
        private static List<Locale> getLocaleListFromJar() {
            List<Locale> locales = new ArrayList<Locale>();
            try {
                URL packageUrl = I18n.class.getProtectionDomain().getCodeSource().getLocation();
                JarInputStream jar = new JarInputStream(packageUrl.openStream());
                while (true) {
                    JarEntry entry = jar.getNextJarEntry();
                    if (entry == null) {
                        System.out.println( "entry was null ");
                        break;
                    }
                    String name = entry.getName();
                    System.out.println( "found : " +name );
                    /*if (resourceBundlePattern.matcher(name).matches()) {
                        addLocaleFromResourceBundle(name, locales);
                    }*/
               }
            } catch (Exception e) {
                System.err.println(e);
                return null;
                //return getLocaleListFromFile(); // File based implementation in case resources are not in jar
            }
            return locales;
        }
    }

    that is the example code off link can i get some what of a explanation of whats happening?


    here is another example witch youes different code.

    My point was that reading a single file from a jar file would be easier than reading the contents of a folder in a jar file. As jps says, the other design would be more OOP. Which way is better for a student is up to the student.

    A JTable for what? I was talking about where to store the questions and answers so they would be easily read and updated.

    jTable for the questions / answers can that store it efficiently? also can it be called from another part of the application, was doing some research and found little a bout jTables.

    JTables are used when the program executes. Not for storing data between executions.

    can a jTable manage like text files, creation, deletion, moding of the files? and reference the variables, or have it saved in all one file so the jTable can lode up with the content of the file in to the jTable and thin dump it all in to that file for the rest of the program to youes it?

    Extract File data into JTable


    what if you have the jTable save by 5 text files each file by column and thin each line a cell, like excel.

    JTables are not connected to files. You would have to write the code to connect a JTable to a file.
