动物特性的OO描述-阶段项目

从面向对象的角度进行分析设计，抽象类和对象的基本方法：

抽取对象的基本的方法：找出句子中所使用的名词

例如：在句子“小猫喵喵叫”中，我们能够确定一个对象：猫；

确定对象发出的行为动作的基本的方法：找出句子中的动词

例如：“旺旺叫”、“喵喵叫”都属于对象发出的动作；

确定对象的属性或者特征的基本的方法：找出句子中的形容词

例如：“哺乳性的”“肉食性的”“卵生的”等等；

“是”的关系一般抽象为继承

例如：狗是一种动物，意味着：“狗”类 继承自“动物”类；

“有”的关系一般抽象为类的属性

例如：动物都有情绪，意味着：“情绪”是“动物”类的一个属性；-Animal characteristics OO Descr iption- phase of the project from the perspective of object-oriented analysis and design, abstract classes and objects of the basic method: extract the object' s basic approach: identify terms that are used in a sentence such as: in the sentence " kitten meow " we can determine an object: cat　determine the object' s behavior actions issued basic approach: identify the verb in a sentence such as:"　Want called " ,"　meow " all belong to the object given action　determine an object' s attributes or characteristics of the basic approach: identify adjectives in a sentence such as: " Breastfeeding nature" , " carnivorous" , " oviparous"　and so on　" is a"　relationship generally abstracted as inheritance example: a dog is an animal, means: " dog"　class inherits from " animal"　class　" yes"　for the relationship between the general abstract class attributes such as: ani
