    Default How to patch a program

    Hellllloooo~ :3

    Lets say I have a program that is not in any way connected to the Internet. I post it for for downloading, but I know that I will need to update it fairly often. I don't want people to have to redownload the entire program, I just want to send out a patch to update it. How can I do this?

    I think the minimal level that changes could be made would be to the replace a class file. If in a jar file, That would require a program to unpack, replace and rebuild a jar file. Updating could be a problem though. If signed, that would be lost. Replacing the whole jar file might be safer.
    Maybe people in the real world have some techniques they use.
    If you don't understand my answer, don't ignore it, ask a question.
