Gui Population w/ Rand function
Greetings,
I'm currently working on a project to create a Trivia game based on movie quotes. I have my code completed, all except the GUI. I'm a bit fuddled as to how to get my GUI to grab the randomly generated information and put it in the fields.
This is what I am envisioning:
I want to have a random question/quote pop up. Then I want 4 random answers to display below it, with Radio or CheckBoxes (which I still havent figured out how to). Once the person clicks their answer they can hit SUBMIT or ENTER, at that point I want it to display if they were correct, if they were NOT correct then display the correct answer and move onto the next question by clicking the NEXT button.
Enclosed is my code (I have a section at the beginning where I have started the process of the GUI code, but just got stumped). Any feedback would be greatly appreciated.
The GUI is a specific element that is required for this project (otherwise I'd just let leave it as is.)

Ok. There's a syntax error right before the constructor, where you declare a type with no identifier.And is this an inner class? I notice that the class is declared private immediately after the imports, which makes me suspect that either something is missing or it's a mistake.
Also, try posting the contents of the text file as you have it. I see that it's a "ZZ" delimited file, but if I create one, I have no way of telling if it's identical to what you're using.

Thanks Joe :)
I left the first part unfinished because I just blanked on how to organize it all.
Here is the text file contents: (very basic quotes)
Have you ever danced with the devil in the pale moon light?ZZBatmanZZWho's Keyser Soze?ZZThe Usual SuspectsZZThere is no spoonZZThe MatrixZZWhy a spoon, cousin?ZZRobin Hood: Prince of ThievesZZWhat do they call you? "Wheels"?ZZX-MenZZHe will bring them death, and they will love him for itZZGladiatorZZI'm gonna make him an offer he can't refuseZZThe GodfatherZZThat's no moon. It's a space stationZZStar WarsZZSo you think you've solved in fourteen days what they couldn't solve in two years?ZZStargateZZIs your father a ghost, or do you converse with the Almighty?ZZBraveheartZZSnakes. Why'd it have to be snakes?ZZRaiders of the Lost ArkZZI will take the Ring to MordorZZThe Lord of the Rings: The Fellowship of the RingZZThe other girls were blonde and delicate and I was a swarthy six-year-old with sideburnsZZMy Big Fat Greek WeddingZZGo back to Jersey Sonny. This is the City of the Angels and you haven't got any wingsZZL.A. ConfidentialZZOur friend T-bird won't be joining us this evening on account of a slight case of deathZZThe Crow
I understand how to create the physical structure of the GUI, but after that I get a bit fuzzy.
I tried to related it to the system.out.print or even JOptionPane but it doesn't seem to function that way.
Sorry for sounding dumb, this is my first big program I've created with a GUI.
I rethought my question maybe this will be a bit clearer.
How do I use ONE GUI Structure multiple times via a FOR LOOP and give that GUI Structure different arguments each iteration of the FOR LOOP?
That ultimately is what I'm looking for and realized my original question sounded befuddled.
Apologies, here is the updated code:

your code have bunch of errors. what exactly movies.txt contains and what are you trying to accomplish?
you have used lots of arrays and i am sure you are lost also like i am.
The movie.txt info can be located two posts above this one.
My intent is also explained in the original post. But my main goal is to create a simple GUI that generates a random movie quote, and 4 random answers. The player answers 10 questions. Thats it really :(
Yeah I thought the array's would be the best way to get random info in without writing an excessive amount of code :( So much for that theory! LOL
Having a huge main method with a bunch of nexted blocks is bad design and makes for very hard debugging. Divide and conquor.
I'd love to, but I have no idea how at this point. Thus the reason I am here, hoping for some structure pointers or maybe a suggestion as to better way to develop the methods.
ok. your first question in the txt file is ?
Q) Have you ever danced with the devil in the pale moon light?
1) Batman
2) Who's Keyser Soze?
3) The Usual Suspects
4) There is no spoon
Am i right?
No, the text file only has Question / correct answer / Question / correct answer....etc.
My trouble is the user defined method "Gooey" I cant seem to get the GUI functioning properly. I'm guessing it is because I'm not using public, private, static, void, whatever correctly
Right now my first compling error is
"Illegal start of expression" refering to the line
public class Gooey extends JFrame
i am just going to submit a demo. may be after that you might want to re think. note i am also not good in swing.
May be this program might be a little help for you. Just to give you an idea about swing. note i am also not good so learning never stops.

Good luck. Overall nice assignment. i wish i have time to do it as you said but may be later on cheers.
