Design Choices

  • All objects are presumed to not be null when passed into a method as a parameter. If an object can be null, use the annotation @Nullable.
  • Syntax:
    • Indent with tabs.
    • Put curly braces on a new line, like so:
    if (blah)
    • If a statement fits in a single line, don't use brackets at all, like so:
    if (blah)
    • ClassesShouldBeNamedLikeThis, as should enums and interfaces. (upper camel case)
    • methodsShouldBeNamedLikeThis, as should non-static or non-final variables. (lower camel case)
    • STATIC_VARS_SHOULD_BE_NAMED_LIKE_THIS, as should any final variables (or variables whose values shouldn't be changed).
  • RecyclerViews are used instead of ListViews. Each RecyclerView should have a separate Adapter class and at least 1 ViewHolder class.
  • TAGs are set on the top of some classes for logging. Set up a shortcut to easily create TAGs for classes by following this article.
  • An "Event" can refer to 2 things, judging on context:
    1. An Event that will occur during orientation week.
    2. Something to notify listeners of. For example, a click event.

Dependencies & Libraries

  • Guava - a Google Library containing lots of helpful classes for Java. Most notably, immutable data structures (like ImmutableList) and EventBus, which provides a way for classes that do not have references to each other to communicate.
  • JodaTime - a library for immutable time objects, unsupported by Java 7. Includes lots of useful data structures and methods; plus, immutable objects are almost always safer when passing by reference.
