Having no previous programming experience whatsoever (Philosophy & Linguistics student), I've decided to take a bunch of intro to programming and Java classes. I'm at the stage where I can read code with some degree of success, but having really hard time writing something from scratch.
Currently working on a problem which is ought to simulate a bookstore, apparently - I've created a few classes and extended them to subclasses, implemented a few methods, etc. It's going good apart from this one thing.
Apologies if it's very basic (which I suspect it is!), here's the gist of it:
So the next step is to construct a method (ShowByGenre) to sort my books by genre (all comedies, then all autobiographies, etc). I have a vague idea how to implement this, but not sure what should I type in first.
ArrayList<Book> BookShelf = new ArrayList<Book>();
But that is a real-world case where you want to rely on as much work done by other people as you can. In a learning environment you might be required to implement your own sorting algorithm. If that is the case - there is a lot on the net about the various algorithms. Your instructor probably told you the name(s) of one or more algorithm, and a little searching should help you figure out what to do. In your specific case, since you are sorting the Genre, for each book you would get the Genre's 'ordinal' - or its order in the BookGenre Enum, and use that for comparison. As a brief glimpse into what it might look like:
