Java libraries you can't afford to miss (Student Day)
summary
A small JavaFX client that queries GitHub repositories demonstrates concrete choices: dependency injection with Guice (or Spring Core), JSON mapping via Lombok + Jackson, HTTP with OkHttp and Retrofit, and async flows first with JDeferred then with RxJava for pagination via Link header so 245 repositories load across pages and sort correctly. Tests use Mockito, Jukito, WireMock (fake HTTP), TestFX (UI) and Awaitility for threads; the app, examples and integration tests are runnable and show the libraries actually wired together.
