Ive been reading Liang's Introduction to Java Programming for a couple of weeks, and that question came up when the author said "There is no need for developers to create, and for users to install, major new software versions.".
How does software update work? For example, patches for games, new version of products, and that kind of things. In the book, there's an example that, as long as you keep an interface of a class the same, you dont need to do any changes in any of the classes that are dependent on the one you changed. That's fine, but still a little abstract (for example, how do I create an update patch with only that class?).
Im also interested in books on the subject.
