Converting Java to Kotlin involves providing Java sources to a tool that applies a 4-step methodology with 5 invariants, adapting constructor styles and annotation targets to ensure Kotlin nullability and mutability while preserving imports and package structure.

Yes, the conversion process handles Spring, Lombok, Hibernate, Jackson, Micronaut, Quarkus, Dagger/Hilt, RxJava, JUnit, Guice, Retrofit, and Mockito by adapting their annotation targets and constructor styles to Kotlin idioms.

Migrating Java constructors and accessors to Kotlin uses a disciplined 4-step methodology with 5 invariants to preserve semantics, adapting constructor styles and accessors to idiomatic Kotlin properties while maintaining the public API.

Kotlin nullability enforcement during conversion applies Kotlin's strict nullability and mutability rules to Java sources, ensuring behavior is preserved while improving readability and safety through a disciplined 4-step workflow.

Yes, the conversion process preserves imports, package structure, and the public API while migrating constructors and accessors to idiomatic Kotlin, ensuring the converted code maintains its original semantic behavior.

The primary limitation of Java-to-Kotlin conversion is that while it uses a 4-step workflow with 5 invariants to preserve semantics, complex custom logic outside of supported frameworks like Spring, Lombok, and Hibernate may require manual verification.
