    Re: talkative

    Please use code tags when posting code.
    Also in what way does it not seem to work, are there any compile time or run time errors or does the field just not update?

    Re: talkative

    Have you tried adding a print statement in the settext method so you can see what text your code is trying to output?

    Re: talkative

    the weird thing is that in the first case, when the file exists the text is modified. Only when the text does not exist the field is not updateing

    Re: talkative

    If you do as I previously asked and post the code in code tags (with each class in their own code tags) I'll look at the code.

    But if it's isn't working when there isn't a file it's probably because you are catching exceptions and then ignoring them - There are very few occasions when this is a good idea. At the very least print the exception stack trace to the console so you can see an exception has been thrown and from where.

    BTW you should use Java coding standards as it makes it a lot easier for you and others to read your code. For example: Class names start with an upper case letter, method names and variables start with a lower case letter and concatenated words have an uppercase letter where they join ie settext should be setText etc

    Re: talkative

    The code you have posted won't even run.

    Your file class creates an instance of the gui class and the gui class creates and instance of the file class so you have a circular dependency which results in a stack overflow.

    Re: talkative

    O..M..G.. not a single exception
    When I run it without a file I get a FileNotFoundException at line 194 of the file class. Of course it would have helped you if you had done what I suggested and printed out the exception's stack trace rather than your own message.

    Re: talkative

    um? im not quite a master at exceptions. I know the minimal. Also, you must create the directory talkative in your c drive containing a resource folder. Inside the resource folder you need a text file called resourcequestions.txt Thank you keang i really appreciate you for dedicating time to me

    Re: talkative

    oh yes, also, it's not so self caring. It cannot create resource folders by himself yet. I'll make such an option later on
