Kotlin: Uncovered
summary
Demos show how Kotlin compiles to JVM bytecode and how that decompiles back into concrete Java: decompile Kotlin bytecode into Java via IntelliJ/Android Studio (Tools → Kotlin → Show Kotlin Bytecode → Decompile). Examples reveal concrete transforms: data class generates componentN copy equals hashCode and synthetic bridge methods, nullable types emit runtime null checks or safe-call ternaries, extension functions become static helpers, delegation stores delegate fields and forwards methods, and inline lambdas produce either invokedynamic‑style calls or synthetic lambda classes.
