说一下数组是对象的观点

  • 先从对象说起,在现实中对象就是一个具体的实物,真实存在的,在JAVA中对象是通过new来创建的,类是对象的模板,是对实物的描述,通过new来把类创建成对象,运行在内存中。学习了数组后会发现,数组也需要初始化,同过new来创建,然后才可以运行,所以数组是对象也是正确的。
  • 我们都知道数组和类都是引用类型,
    -例: classname name = new 构造器();
  • 看例子可以知道这样成功的创建出了对象 name是对象名 也是引用类型的变量 这个变量是指向了对象的地址。
  • 同理 type[] name = new type[1];
  • 这样也是创建了数组对象,name也是指向了对象的地址。
