java 8 released!!

여전히 감이 안오는 람다이긴 하지만.
JDK1.8 부터 지원을 한다는데..

1.5 처럼의 대격변은 아니라서 다행인지도?

Java Programming Language Lambda Expressions, a new language feature, has been introduced in this release. They enable you to treat functionality as a method argument, or code as data. Lambda expressions let you express instances of single-method interfaces (referred to as functional interfaces) more compactly. Method references provide easy-to-read lambda expressions for methods that already have a name. Default methods enable new functionality to be added to the interfaces of libraries and ensure binary compatibility with code written for older versions of those interfaces. Repeating Annotations provide the ability to apply the same annotation type more than once to the same declaration or type use. Type Annotations provide the ability to apply an annotation anywhere a type is used, not just on a declaration. Used with a pluggable type system, this feature enables improved type checking of your code. Improved type inference. Method parameter reflection. Collections Classes in the new java.util.stream package provide a Stream API to support functional-style operations on streams of elements. The Stream API is integrated into the Collections API, which enables bulk operations on collections, such as sequential or parallel map-reduce transformations.
