Revisiting Effective Java in 2019
summary
Covers Effective Java 3rd edition with live coding that compiles and runs, demonstrating immutable value objects via factory methods over constructors, equals/hashCode pitfalls and caching, toString vs Formattable for business format, Comparable and comparator optimizations, and use of Guava and mentions Lombok/Immutables. Emphasizes Java 8 features: counts 41 functional interfaces but focuses on six core ones, shows five method reference types, and rewrites enum-based singletons into a lambda-backed enum singletons/strategy pattern. Source code lives on GitHub and examples execute during the session.
