    Default Permanently change variable values based on user input.

    Hey everyone, I've been working on a project with a friend of mine and we're trying to create a program that spits out information based on information about a situation that the user is currently in. We have all these things that have a certain probability to be chosen based on a score that we have created. We're trying to implement a system in which after all the situations are over the user will tell the computer whether or not the information it put out was good or bad. Based on this answer the computer will change the score of the sets of information that it chose so that it knows they worked in that situation. I'm decently new to java and I don't know of any way to permanently change a variable in a system without going in and changing it in the actual code. Does anyone have any tips?

    I don't quite understand what you are trying to do, or what your question is

    way to permanently change a variable in a system
    Nothing is permanent in or on a computer. Every value can be edited or rewritten.
    You'll have to explain where the value is that you want to change and how you expect that value to be kept unchanged in the future.
    If you don't understand my answer, don't ignore it, ask a question.

    Maybe you can try something like the following:

    1. When the application starts, have it look for a certain file in a certain place with certain contents.

    2. If the file does not exist, set the relevant variable values to appropriate defaults.

    3. If the file does exist, read in the values previously saved in the file.

    4. When the program want's to "change the score of the sets of information" (whatever that means), have the program write the relevant values to the file.



    Of course, the change won't be truly "permanent," but it will say in effect until the next time the program decides that it needs to "change the score of the sets of information" (whatever that means).

    Furthermore, if you make the file a human-readable (text) file, you can create the file off-line (with a text editor) with whatever values you have previously found (by simulation or whatever) before you run the application.



    Cheers!
