Design Patterns with Kotlin
summary
Shows concrete conversions of Gang of Four patterns to Kotlin using IntelliJ’s Java→Kotlin converter and Kotlin→Java decompiler, demonstrating fewer lines and real tradeoffs: object singletons replace classic patterns and compile to lazy, reflection-safe Java; default parameters often remove the need for builders; nullability forces use of the Elvis operator; delegates.observable and reified generics replace boilerplate; Dagger integration works via generated code. Presents specific code-level differences and gotchas rather than high-level promises.
