java

Java语言（17+）。涵盖现代特性、模式和最佳实践。在编写Java应用程序、Spring Boot后端或企业系统时使用。使用条件：用户提到“java”、“records”、“sealed classes”、“streams”，询问关于“模式匹配”、“switch表达式”、“Optional”、“集合”、“泛型”。不用于：Spring Boot具体细节 - 请改用backend-spring-boot技能；不用于：Lombok注解 - 请改用lombok技能；不用于：MapStruct - 请改用mapstruct技能

Java language (17+). Covers modern features, patterns, and best practices. Use when writing Java applications, Spring Boot backends, or enterprise systems. USE WHEN: user mentions "java", "records", "sealed classes", "streams", asks about "pattern matching", "switch expressions", "Optional", "collections", "generics" DO NOT USE FOR: Spring Boot specifics - use backend-spring-boot skill instead DO NOT USE FOR: Lombok annotations - use lombok skill instead DO NOT USE FOR: MapStruct - use mapstruct skill instead
