Hot and spicy Java with Lombok. Live!

on YouTube ↗54m

" summary

Demo shows how Lombok generates constructors, getters/setters, @Builder and other patterns at compile time via annotation processors (javac and Eclipse Java compiler), plus the IDE plugin for completion; using delombok reveals the actual bytecode and produced code. A 3.7KB whiskey class shrinks about fourfold after annotations. Features shown: @Data/@Value, @Accessors, @Singular, @Synchronized, @SneakyThrows, logging annotations. Warnings: equals/hashCode changes, hidden method modifications, need to enable annotation processing and support two compilers, and use magic cautiously.
