FAQPage Schema
How do I implement a sealed class hierarchy with exhaustive when expressions in Kotlin?▼

To implement a sealed class in Kotlin, define the class using the `sealed` modifier and utilize exhaustive `when` expressions to handle all subtypes. This Skill provides syntax references and code snippets for Kotlin 2.x to structure these hierarchies effectively.

What is the best way to build a fat JAR using Gradle or Maven?▼

Building a fat JAR involves configuring your build tool to bundle all dependencies into a single archive. This Skill assists with Gradle and Maven commands for dependency management and packaging, streamlining the build process for JVM applications.

Can I use jlink and GraalVM native-image to optimize and package JVM applications?▼

Yes, `jlink` assembles custom runtime images and GraalVM `native-image` compiles Java or Kotlin code into standalone executables. This Skill supports these JVM tooling utilities to reduce package size and startup time.

Does this Skill support modern Java 21 LTS features and syntax?▼

Yes, this Skill provides quick reference for modern Java 21 LTS features. It assists developers by offering syntax examples and language feature support to streamline JVM programming without manual lookups.

How do I execute common build and testing tasks for Java and Kotlin projects?▼

Executing build and testing tasks requires running specific commands in your build tool. This Skill supports Gradle and Maven integration, helping you quickly manage dependencies, build projects, and run tests on the JVM.
