Interfaces with Skeletal Implementations in Java

نویسنده

  • Markus Mohnen
چکیده

Java’s interfaces allow the definition of class properties independently of class inheritance. Since interfaces allow multiple inheritance, their potential for reusable code is higher than those of abstract classes. We present a technique for augmenting interfaces with skeletal implementations by using Java’s inner classes. Using this technique, we propose an extension of Java for providing skeletal implementations in interfaces.

Interfaces with default implementations in Java

With the interface construct, Java features a concept with high potential for producing reusable code: Java’s interfaces allow the definition of class properties independently of class inheritance. We propose an extension of Java for providing default implementations in interfaces. Default implementations are useful since they reduce the effort required to implement an interface. They are espec...

Working with Java Interfaces and Classes How to maximize design and code reuse in the face of inheritance

Software engineering has been using interfaces for over 25 years. The distinction between interfaces and implementations is an important issue of object-oriented software system design. Java supports this distinction, yet for many developers, in particular with a C++ or Smalltalk background, the proper use of interfaces may not be intuitive right from the beginning. This article briefly discuss...

JavaGI : Generalized Interfaces for Java

JavaGI is an experimental language that extends Java 1.5 by generalizing the interface concept to incorporate the essential features of Haskell’s type classes. In particular, generalized interfaces cater for retroactive and constrained interface implementations, binary methods, static methods in interfaces, default implementations for interface methods, interfaces over families of types, and ex...

Working with Java Interfaces and Classes How to separate interfaces from implementations

Software engineering has been using interfaces for over 25 years. Java, in contrast to other object-oriented programming languages like C++ and Smalltalk, provides a clean separation between interfaces and classes that implement the interfaces. For new Java developers, this requires some adjustment in thinking. This article shows not only how to distinguish between interfaces and classes, but a...
