New是一个Java编程的关键字,使用了之后会返回一个object reference of the created object。 我们已经强调过很多次了,建立一个object之后,必须把object reference的值存下来,这样才能在日后访问object。建立一个object的方法就如同这张PPT的最后一行:先声明一个这个类的object reference,在用new关键字创建一个object,...

1>.第一种是Java为我们提供好的,如Scanner,Random,Math类等等,这些以及存在的类中包含了很多的方法与属性,可供我们使用。 2>.第二种是我们自己创建的类,按照类的定义标准,可以在类中包含多个方法与属性,来供我们使用,本篇博客以及后面更新的关于面向对象编程的内容基本上都是在介绍第二种的简单使用。
