Declaration(声明部分),如上述的Point originOne,Rectangle rectOne。 Instantiation(实例化部分),也就是 new 关键字,它是一个创建对象的Java操作符。 Initialization(初始化部分),new操作符之后是对构造函数的调用,该调用初始化新对象。 下面将会按照这三个部分进行讲解。 Declaring a Variable to Refer to an Objec...
而提到hashCode方法就不得不提 Java 中的Map接口下的相关容器了,因为Map接口下的一些容器(HashMap,IdentityHashMap)正是通过对象的hashCode方法进行工作的,在HashMap中,会有一个名为table的数组字段,这个数组字段用来储存HashMap中每一个键值对关系,即为映射表,每当储存一个新的键值对进入当前的HashMap对象的时候,都...

Object类中有一个getClass方法,m a r k- t o- w i n:它会返回一个你的对象所对应的一个Class的对象,这个返回来的对象保存着你的原对象的类信息,比如你的原对象的类名叫什么,类里有什么方法,字段等。在高级编程当中用的很多,和反射相关。马克-to-win:现在这个阶段还说不清楚,只能先打个比方,反射就像镜...
