  "summary": "The Java 21 release introduces two powerful features, Records and Pattern Matching for switch, which significantly enhance code readability and maintainability. Records provide a concise way to create immutable data carriers, automatically generating essential methods like equals, hashCode, and toString. Pattern Matching for switch enables more expressive and concise conditional logic, reducing the need for manual type checks and casting. A real-world refactoring case demonstrates how a legacy codebase, filled with verbose class hierarchies and complex conditional structures, can be transformed into a self-documenting design using these modern Java features. The new approach not only minimizes code duplication and runtime risks but also aligns with Google Java Style standards, making the codebase more readable and easier to maintain.",
