Abstract : Java 8 was released recently. Along with lambda expressions, a new language construct is introduced: default methods in interfaces. The intent of this feature is to allow interfaces to be extended over time preserving backward compatibility. In this paper, we show a possible, different use of interfaces with default methods: we introduce a trait-oriented programming style based on an interface-as- trait idea, with the aim of improving code modularity. Starting from the most common operators on traits, we introduce some programming patterns mimicking such operators and discuss this approach.
