Java APIs - the Missing Manual
summary
Shows concrete Java SE techniques: how to register implementations via META-INF/services and load them with ServiceLoader (noting implementations need no-arg constructors and Java 9 modules can use provides/uses), how to design custom annotations and annotation processors (use @Target and @Retention(RetentionPolicy.RUNTIME), read values with reflection, and generate files at compile time), and practical patterns for handling exceptions in streams (wrap results in success/failure objects or use libraries like Vavr so one bad element doesn’t break the pipeline).
