What it does
Use when converting Java source files to idiomatic Kotlin, when user mentions "java to kotlin", "j2k", "convert java", "migrate java to kotlin", or when working with .java files that need to become .kt files. Handles framework-aware conversion for Spring, Lombok, Hibernate, Jackson, Micronaut, Quarkus, Dagger/Hilt, RxJava, JUnit, Guice, Retrofit, and Mockito.
Java to Kotlin Conversion
Convert Java source files to idiomatic Kotlin using a disciplined 4-step conversion methodology with 5 invariants checked at each step. Supports framework-aware conversion that handles annotation site targets, library idioms, and API preservation.
Workflow
digraph j2k_workflow {
rankdir=TB;
"User specifies files" -> "Step 0: Scan & Detect";
"Step 0: Scan & Detect" -> "Load framework guides";
"Load framework guides" -> "Step 1: Convert";
"Step 1: Convert" -> "Step 2: Write .kt";
"Step 2: Write .kt" -> "Step 3: Git rename";
"Step 3: Git rename" -> "Step 4: Verify";
"Step 4: Verify" -> "Next file?" [label="pass"];
"Step 4: Verify" -> "Fix issues" [label="fail"];
"Fix issues" -> "Step 1: Convert";
"Next file?" -> "Step 0: Scan & Detect" [label="batch: yes"];
"Next file?" -> "Done" [label="no more files"];
}
Step 0: Scan & Detect Frameworks
Before converting, scan the Java file's import statements to detect which frameworks are in use. Load ONLY the matching framework reference files to keep context focused.
