详细解析Java中抽象类和接口的区别

详细解析Java中抽象类和接口的区别(中文3300字,英文2300字)
在Java语言中，abstractclass和interface是支持抽象类定义的两种机制。正是由于这两种机制的存在，才赋予了Java强大的面向对象能力。abstractclass和interface之间在对于抽象类定义的支持方面具有很大的相似性，甚至可以相互替换，因此很多开发者在进行抽象类定义时对于abstractclass和interface的选择显得比较随意。其实，两者之间还是有很大的区别的，对于它们的选择甚至反映出对于问题领域本质的理解、对于设计意图的理解是否正确、合理。本文将对它们之间的区别进行一番剖析，试图给开发者提供一个在二者之间进行选择的依据。

Parsing Java Abstraction of the Difference Between Classes and Interfaces

In Java language, abstract scale-up and with support class abstraction definition of two mechanisms. Because of these two kinds of mechanism of existence, just gives Java powerful object-oriented skills. Abstract scale-up and with between class abstraction definition for support has great similarities, even interchangeable, so many developers into line nonabstract class definition for abstract scale-up and it is becoming 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 understand correctly and reasonable. This paper will for the difference analysis, trying to give a developer with a choice between them are based. [来源：http://www.doc163.com]
