Tall Legacy App with 10 Pumps Kotlin
summary
Concrete recipes for Kotlin Java interop with examples and pitfalls using real bytecode and generated methods The talk shows how annotating top level files with @JvmName and @JvmMultifileClass consolidates helpers into a single utils class so Java callers keep existing names It demonstrates data class access via @JvmField and consts to avoid getters, object singletons exposed as statics with @JvmStatic, and how @JvmOverloads creates N overloads for default parameters (no skipping middle args) plus using @Throws to produce checked exceptions Java can compile against
