SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Helps teams ensure Java 17+ code adheres to idiomatic patterns such as immutability, records, sealed classes, pattern matching, and modern language features, especially during reviews and collaboration.

Core Features & Use Cases

  • Immutability First: default to final fields and unmodifiable collections to reduce mutability risk.
  • Records and Sealed Classes: guidance on when to use records and sealed hierarchies for clear value objects and closed type hierarchies.
  • Pattern Matching & Switch Expressions: promote pattern matching and switch expressions for concise, type-safe control flow.
  • Naming, size, and testing: enforce naming conventions, method length limits, and testing practices to improve readability and maintainability.
  • Use cases: apply these standards across code reviews and during refactoring to align with Java 17+ features.

Quick Start

Review your Java 17+ codebase and begin applying immutability, records usage, sealed classes, and modern language features to align with these standards.

FAQPage Schema
How do I enforce Java 17 coding standards for immutability and records during code reviews?

Use Java 17 coding standards to enforce immutability and records during code reviews by defaulting to final fields and unmodifiable collections, reducing mutability risk and ensuring codebase consistency.

What is the best way to apply sealed classes and pattern matching in Java 17+ projects?

The best way to apply sealed classes and pattern matching in Java 17+ projects is to use sealed hierarchies for closed type hierarchies and switch expressions for concise, type-safe control flow. This promotes clear value objects and modern idiomatic code.

When should I use Java records instead of traditional classes for value objects?

You should use Java records instead of traditional classes for value objects when you need clear data carriers. Java coding standards recommend records to reduce boilerplate and enforce immutability, aligning with modern Java 17+ idiomatic patterns.

Can I use Java coding standards to check naming conventions and method length limits?

Yes, you can use these Java coding standards to check naming conventions and method length limits. The standards codify guidelines for naming, size, and testing practices to improve readability and maintainability across your codebase.

Do I need to refactor existing code to align with Java 17+ switch expressions and sealed hierarchies?

You need to refactor existing code to align with Java 17+ switch expressions and sealed hierarchies if you want to achieve type-safe control flow. Applying these standards during refactoring helps modernize your codebase effectively.
