    Lightbulb solved.

    I have some java questions. I made a game that has two balls. One that you control and one that moves around the screen. You have to avoid getting hit by the moving ball.
    So far, I just have a ball moving around and the one that you control. When you get hit by the moving ball, I made it so that the game redirects to JPanel. This jpanel contains questions (education purposes).
    My question is: how do I load a text file with questions in this format:
    the text file:

    What is bob + 2?
    A) x5
    B) c8
    C) 1337
    D) 15555

    What is new+bie?
    A) Newbie
    B) noob
    C) loser
    D) donaldmax

    and so on. i have around 35 questions.

    So far the panel i made has 4 radiobuttons on a gridlayout of 5,1. the 4 radio buttons do this right now:

    A)
    B)
    C)
    D)

    I am trying to put a text area containing a question from the question.txt file and the four answer choices in the corresponding radio buttons(a,b,c,d). how would i be able to do this?
    Also how do i make the ball move faster? (the moving one) every 20 seconds. im using a thread currently. im a newbie at java :/



    thank you! any comments and tips are appreciated. if you need more information please post and say so !

    solved!

    I get 11 errors when I compile this code. Is that what I should expect?

    commented out the text reader stuff
    You should write a small testing program that does just the text reader stuff to get the techniques and classes to work like you want it to. Then move the code into the larger program.

    The Scanner class would be an easy way for a simple file.
    The other file reading classes get more complicated.

    I made a game that has two balls.
    How are you controlling the ball movement now?

    If you're using a timer in the thread, reduce the timer delay; if you're just sleeping the thread in a loop, reduce the sleep time.

    Incidentally, when posting code, please use the Java Naming Conventions - class names begin with an uppercase letter, method and variable names begin with a lowercase letter. If you don't follow the convention, people will be confused reading your code, and people like me won't read it at all.
