java functional interface
Functional interfaces provide target types for lambda expressions and method references. Each functional interface has a single abstract method, called the functional method for that functional interface, to which the lambda expression's parameter and,An informative annotation type used to indicate that an interface type declaration is intended to be a functional interface as defined by the Java Language Specification. Conceptually, a functional interface has exactly one abstract method. Since default

函数式接口(Functional Interface)是Java 8对一类特殊类型的接口的称呼。 这类接口只定义了唯一的抽象方法的接口（除了隐含的Object对象的公共方法）， 因此最开始也就做SAM类型的接口（Single Abstract Method）。 为什么会单单从接口中定义出此类接口呢？ 原因是在Java Lambda的实现中， 开发组不想再 ... http://colobu.com Java 8 Functional Interfaces - TutorialsPoint
