一、Iterable
Iterbale是一个具有迭代功能的泛型接口,可以通过for-each循环,从Iterable获取Iterator或者通过Iterable的for each()方法
二、Collection
1.Collection继承于Iterable的泛型接口,用来实现集合的接口。
2.Collection是不一定具备线性结构的特点。线性表是一种Collection,非线性表也是一种Collection。

三、List
1.List是一个接口,接口不能进行实例化,只能引用实现其接口具体的类
2.List是一个线性表,即n个相同类型元素的有限序列,在该序列上可以进行增删查改以及变量等操作,元素有顺序,List具备迭代能力,具备装元素的能力
