Common method signatures and meanings of Iterable, collection and list

Let's tidy up today , We Java Big brother in the collection Collection Interface and its parent interface Iterable, A subinterface List.

Iterable What is it? ？

It can be said to be the interface at the top of the collection framework , Implement traversal of the set .

Collection What is it? ？

It is the root interface in the hierarchy inherited from Iterable, The parent interface is not used for specific implementation , It defines some public specifications for the following specific implementation interface classes .

List

list Is an ordered set, also known as sequence , Inherited Collection Interface , It's also an interface , It cannot be used to instantiate objects , So his following realization ArrayList,LinkedList,Stack Many kinds
List Official documents

ArrayList

ArrayList Realized List, It's a sequence table , It is the simplest data structure , Is a set of the same data type, that is, an array , His logical structure and physical structure are continuous .

LinkedList

LinkedList Realized List, Linked list ,Java Medium LinkedList Realized the bidirectional linked list , queue , deque , These are linear structures , Although their logical structure is continuous, they are not continuous in physical structure

Stack

Stack Realized vector,vector Realized List, therefore Stack It has also been realized. List, It's a stack , Stack in data structure , It is also a linear structure. Like queues, it is a special linked list .
