1.Object-Oriented Programming(OOP:面向对象编程) 1.An object has a unique identity, states, and behaviors.属性与行为 2.Objects can interact with each other for computing tasks.对象之间的交互 用开车来类比 step1:declaration 1.Class: when programming in Java, we begin by declaring a program unit...
相比之下,object reference(不管指向的是哪一个类的)的大小已经被Java规定好了,都是固定的,那么array中存放object reference的时候,分配的区域就不会是特别特别大。 第三句话说:array的大小是在运行的时候被确定的。这个话不是很重要。 第59页: Array在Java语言中,是一个class,想要使用Array class中已经编写好的...
