Boxing Conversion in J2SE 5.0 Here autoboxing plays a different role, choosing a most-specific method when more than one method is applicable for method invocation. If you call testMethod() with a primitive long parameter, then the first testMethod() is used. If you call testMethod() with an Integer object parameter, then the second testMethod() is used.

Clojure is a dynamic programming language that targets the Java Virtual Machine (and the CLR, and JavaScript). It is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. Clojure is a compiled language - it compiles directly to JVM bytecode, yet remains completely dynamic. Every feature supported by Clojure is supported at runtime. Clojure provides easy access to the Java frameworks, with optional type hints and type inference, to ensure that calls to Java can avoid reflection. Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system.
