I would like to create a quiz for my Java GUI.
I'd like it to display a question on one page, then have a next button which takes the user to another page telling them if that question was correct or not, and if it is correct they can move on to the next question (by clicking another next button) and if they got it wrong, have to go back and answer it again. However I have no clue how to do this!!
So far I have a simple GUI with a welcome page and tabs down the side, one of which includes a quiz. Would it be a better idea to create the quiz in Flash or something and then embed it into my Java application? Or just do the whole thing in Java? I'm really new to java so I'm not at all sure what to do, any help would be greatly appreciated!
Thanks
It would be best to use just Java. Consider using CardLayout with your GUI to allow swapping questions, or else you can create and modify key components on the fly such as the text displayed by JLabels and JRadioButtons.
Key though before considering any GUI structures is to first create solid OOPS based non GUI classes to handle your questions. For instance, you may want classes for:
Question class that holds a question String, a List of possible answer Strings, a correct answer String. This class can randomly order the incorrect and correct answers, can have a method for checking if the answer selected is correct.
A Test class that holds a collection of questions, that can present questions in random order, that can hold the score obtained.
A QuestionReaderWriter class that can read and write questions to a text file (you definitely do not want to hard-code the question text).
For this type of app it would be best to use the language you are more familiar with.
Since this is just a simple display this then do that there really is nothing very difficult about it.
Personal, I would lean towards Flash as the flash IDE is drag and drop and an experienced flash guru could make this in a few hours. Flash IDE is geared towards this.

I'm working on one of my first java applets and I want to start of fairly simple (though I have a good understanding of how code works I dont know much in terms of what methods I all have at my disposal when using java)
I have created a Jframe window that has a JTextarea in it. I would like to execute certain lines of code when certain things are typed into this box. In essence, its a simple text input system. How would I go about doing this or is there a better component to use for this?
in addition to getText(), for JTextField some prefer the getDocument() method. In Java, Listeners are used to capture events, such as "what was typed to the text area". This tutorial will get you started, if you have trouble implementing you can come back with a more specfic question and some code :)
I am working on a simple Java applet multiple choice quiz that will display a question with three choices. I am pulling the questions and answers from a text file and want to loop through the questions as the user answers them. So every time the user hits 'Submit' the program will check the answer then update the labels with a new question. My question is how do I get the loop to wait on the answer? Should I put all of the code in the button event handler? I thought about Cardlayout, but it seemed inefficient. I don't really have any code yet; I'm still in the planning stage. Thanks!
I would suggest:
First of all regarding, "My question is how do I get the loop to wait on the answer?", I wouldn't even use a for-loop or any similar loop to solve this.
I would create a non-GUI class to hold each question, the possible answers and the correct answer. Consider calling it Question. It would have a String field for the question itself, a List<String> for possible answers, and either another String for the correct answer, or it could hold an int for the index to the correct answer, or even have the correct answer always be the first one, and be sure to randomize the display of answers.
Create an ArrayList of this class, ArrayList<Question>.
Read in the file all at once, filling your ArrayList.
Give your main GUI class an int index variable for iterating through this ArrayList.
When a submit button is pressed, increment your index and get the next item in the List (if not at the size limit of the List).
Consider creating a JPanel class for displaying each question and the possible answers, perhaps called QuestionPanel.
You can either create one display object and swap out the text of your question JLabel and the text of your JRadioButtons. This works nicely if all questions have the same number of possible answers.
Or you could create multiple QuestionPanels, and swap them via CardLayout.
There's nothing "inefficient" about a CardLayout. I have no idea what you're talking about here. Care to elaborate what is inefficient about it, and just what you mean by the term "inefficient"?
As a way of learning Java, I'm writing this little application for grade schoolers to practice basic math. The idea is that the kid does any number of math problems, as long as they are in the app, it just continues to throw problems at them until they click a 'Done' button. When they decide to be done, I want a new JFrame to come up that will show them all of the problems they attempted, along with their answer, and whether they got the problem right or wrong.
The advice that I am looking for is what is the best way for me present these results. I looked into the GridLayout and the GroupLayout, but I don't think that these are exactly right. I did something similar in VBA for Excel, and there I just ran a for loop with one iteration for every problem they attempted. Each iteration would add a row of labels to the frame with the elements of the problem displayed in the various labels. I tried this in Java, but I'm not even able to get the labels to even display.
So before I get all specific and start posting my code, I want to ask a bigger question, which is "what is the best method to create a view like this?" Often, I go off in one direction only to waste time before somebody suggests a totally different (and better) approach.
Thanks!
(edit: here's an image of how I did this in Excel. I'm trying to repeat basically the same thing in Java)
One simple way to make that design would be to use a mix of components. You could have a bunch of JLabels and JPanels stacked in a vertical FlowLayout. The grid you have described would be best designed in a JTable, something like the below:
If you like tables like Excel then, Java provides JTable class to create tables, if you want.

I need to make kind of a game in Java but I am a total beginner. It has to be applicable to the web and I need to use images on it and action listeners. So, do you recommend any site to know how to begin?
The description of the game (it is not really a game but it implements things that usually are in a game) is this:
Show a matrix of images of 3x3 elements, then, hide them and put instead empty squares. The images shown in the matrix, must remain in the lower part of the screen just below the empty squares and they must be randomly positioned. The user, must click one image and put it on the correct empty square. The result, must be, how many images were correctly positioned, the time it took to end the game, the time between mouse clicked and released for each image.
For additional information, I want you to know that this application is for a friend of mine who studies medicine. He wants this program to test patients who accident and receive hits on their heads. You may think that the description I gave you may not be a good software for that purpose, and in fact, it may be not, but, once I know the management of all that is required (Images, MouseListeners, how to introduce it to a web etc), I will be able to make a better product. So, please tell me, how can I begin?. What do I need to know?
I would start here. Except for some startup boilerplate and the restrictions of the sandbax (which, based on your description, you will b unlikely to encounter), there is no fundamental difference in an applet from normal code.
I will explain my question clearly.
I need to zoom in/zoom out the world map.
When I click on the particular country in map, control should redirected to new page with respective the country.
I dont have any idea about this in java. Please explain the steps to acheive the above task.
As the question is quite general, here is a general answer: Zooming often means, that you want to display a certain percentage of somethin, and not the whole, where your size of the displayed will not change.
But in your case it seems more like a "find a mouse click in a polygon" thing. So you have to add a selection/click listener to whatever widgets you use (Swt? swing? ....?) where you change what your program renders.
It sounds like you may be trying to reinvent the wheel. Google etc have already solved this problem rather well. It might be better to incorporate an existing solution into your application. Have a look at GoogleEarth inside Java Swing.
