【正文】 derstanding no problems, for example: we through for problem domain analysis found that AlarmDoor in concept in essence and filled is consistent, then we realize when he failed to correct reveal our design intention, because in these two concepts on the definitions (both use with defined) reflect reflected these meanings. If we in problem field understanding is: AlarmDoor in concept is essentially, at the same time it is filled with alarm function. How should we e to the design, realization to clear reflect what we mean by this? Front has said, in Java language abstract scaleup said in an inheritance relationship, and inheriting relationship is in nature is a relationship. So for held this concept, we should use abstract scaleup way to define. In addition, AlarmDoor has alarm functions, that it will be able to acplish alarm concept definition of behavior, so alarm concept can be through with defined. This realization basically can clearly reflect our for problem domain, the correct understanding of our design intent reveals. Actually the abstract scaleup says is is a relationship with said, was like a relationship, everyone when the choice can be used as a basis, which, of course, is based on understanding the problem domain, for instance: if we think AlarmDoor in concept is essentially alarm, have again at the same time, then held the function of the above definition way will in turn. Summary 1. Abstract scaleup in Java language suggests is a kind of inheriting relationship, a class can be used only once inheritance relationship. However, a class but can implement multiple with. 2 in the abstract scaleup may have their own data members, also can have the members of the abstract method, while in with, can have only static cannot be modified data members (. must is static, immigration, but in with generally doesn39。 two concepts are used with defined。Parsing Java Abstraction of the Difference Between Classes and Interfaces In Java language, abstract scaleup and with support class abstraction definition of two mechanisms. Because of these two kinds of mechanism of existence, just gives Java powerful objectoriented skills. Abstract scaleup and with between classes abstraction definition for support has great similarities, even interchangeable, so many developers into line nonabstract class definition for abstract scaleup and it is being more casual with choice. In fact, both between still has the very big difference, for their choice even reflected in problem domain essence of understanding, to design the intentions of the understanding correctly and reasonable. This paper will for the difference a nalysis, trying to give a developer with a choice between them are based. Understand class abstraction Abstract class and interface in Java language is used for abstract classes (in this article nonabstract class not from abstract scaleup translation, it represents an abstract body, and abstract scaleup for Java language used to define class abstraction in one way, please readers distinguish) defined, then what are the abstract classes, use abstract classes for us any good? In objectoriented concept, we know all objects is through class to describe, but in turn not such. Not all classes are used to describe object, if a class does not contain enough information to portray a concrete object, this class is abstract classes.
