SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill ensures that Java code is written, refactored, and reviewed to be production-grade, strictly adhering to the project's configured language level and best practices.

Core Features & Use Cases

  • Language Level Adherence: Automatically detects and follows the project's Java version (e.g., from .tool-versions, pom.xml, build.gradle).
  • Code Quality: Enforces naming conventions, type safety, resource management, and modern Java features.
  • Testing Best Practices: Guides on writing self-contained, well-structured tests using JUnit 5 and Mockito.
  • Use Case: Refactor a legacy Java method to use modern features like var and try-with-resources, ensuring it remains compatible with the project's Java 11 standard.

Quick Start

Use the java-language skill to refactor the provided Java code snippet to adhere to Java 17 standards.

FAQPage Schema
How do I refactor legacy Java code to use modern language features while staying compatible with my project's Java version?

Refactoring legacy Java code involves detecting the configured language level from build files like `pom.xml` or `build.gradle`, then applying modern features like `var` and `try-with-resources` while ensuring strict compatibility with that target Java version.

What are the best practices for writing production-grade Java code for API design and concurrency?

Production-grade Java code enforces naming conventions, type safety, and strict resource management, while carefully handling API design, core language features, and concurrency to ensure readability, performance, and robust execution.

How do I write self-contained Java tests using JUnit 5 and Mockito?

Writing self-contained Java tests with JUnit 5 and Mockito requires following modern testing patterns, structuring tests well, and ensuring they remain isolated and self-contained to validate code behavior effectively.

Does this Java code review approach automatically detect the project's configured language level?

Yes, Java code review automatically detects the project's configured language level by reading configuration files like `.tool-versions`, `pom.xml`, or `build.gradle`, ensuring all code strictly adheres to the detected Java standard.

Can I use this approach to enforce type safety and naming conventions across my Java project?

Yes, you can enforce type safety and naming conventions across a Java project, as this approach strictly adheres to configured language levels and best practices to maintain high code quality and readability.
