Summary

In September 2023, Java released its latest LTS version (Java 21) which brought numerous new features aimed at improving performance and clarity in the code base. However, taking advantage of these changes can be challenging due to unfamiliarity with the new features. To assist developers, Sonar has introduced a group of new Java 21 rules that guide users from the beginning of their coding journey. These rules cover various aspects such as using built-in "Math.clamp" methods, correct ranges with Math.clamp, SequencedCollection reversed() for reverse iteration order, and more. By adopting these rules, developers can ensure proper usage of new improvements, avoid bugs, and improve code quality.
