Java and Kotlin

Purpose

Write JVM code that uses the modern language surface — records, sealed types, pattern matching, coroutines — instead of the 2010-era idioms most JVM codebases are still carrying.

When to Use

• Writing or reviewing Java 17+ or Kotlin.
• Migrating a codebase off Java 8 idioms.
• Designing domain models with records and sealed interfaces.
• Introducing coroutines to replace callback or thread-pool code.
• Diagnosing JVM memory, GC, or startup problems.
