modern-java

To modernize legacy Java, you transform existing patterns into idiomatic code by applying records, sealed classes, pattern matching, and text blocks. This reduces boilerplate and increases safety for projects targeting Java versions 11 through 25.

The best way to adopt modern Java syntax is to apply features like enhanced switches, local-variable syntax in lambda parameters, and modern APIs like HttpClient and Stream.toList during code reviews or refactoring sessions. Ensure your project's Java configuration supports the targeted versions 11–25.

Yes, you can use modern Java features like text blocks and HttpClient if your project is configured for Java 11 or higher. The transformation requires targeting Java versions 11–25 and ensuring all applied features are supported by your project's specific Java configuration.

Pattern matching in Java simplifies code reviews by validating modern Java usage and ensuring adherence to modern idioms. It reduces boilerplate and increases safety by allowing reviewers to check if legacy patterns have been correctly transformed into idiomatic modern syntax.

You should not use modern Java features when your project's Java configuration does not support the targeted versions 11–25. Applying features like sealed classes or pattern matching without ensuring compatibility will break your codebase and fail the modernization process.
