[157] Supporting lambda expressions also permits useful-model functions on streams of factors, such as MapReduce-inspired transformations on collections. Default strategies may be used by an writer of an API to add new techniques to an interface without the need of breaking the aged code applying it. even though it wasn't their primary intent,[152] default strategies can also be utilized for many inheritance of habits (but not condition).
Interfaces and Inheritance describes interfaces—whatever they are, why you would probably want to write down a single, and the way to create one. This section also describes the way in which you'll derive a single course from An additional.
