What data structures are useful for storing comic information like chapters and pages?

A combination of data structures is often best. You could use a `List` or `ArrayList` to store a collection of comic chapters. Each chapter could be represented as a `HashMap` or custom class mapping chapter ID to a list of pages. Each page would then be a `Bitmap` or a reference to a `Bitmap`, and you might need a separate structure to store metadata like page number and panel layout.
