The list interface inherits from the collection interfacehas three major characteristics:1. ordered set : the same order of deposit and withdrawal2. users of this interface can have precise control of where each element in the list is inserted : can be manipulated by index3. can store duplicate elementsUnique methods f
List interfaceUsers of this interface can precisely control the insertion position of each element in the list. The user can access the element based on the integer index of the element (where it is located in the list) and search for the elements in the list.Characteristics:Orderly access to elementsThe collection can
Today, I saw this remark on the internet, saying that "the Java stack class implements the design of the list interface is a joke." Of course, the author of this article is not the focus of this, originally I was just laugh, but there are still people to see the comments echoed, said "Java The design of the stack as a joke, almost can be counted", I am a bit not calm, why, when "as a joke" and "almost can b
The list, set, and map interfaces are frequently used in Java to summarize the followingTheir inheritance and implementation relationships are as follows:Collection├list│├linkedlist│├arraylist│└vector│└stack└setMap├hashtable├hashmap└weakhashmapAn excerpt from an article, reproduced http://blog.csdn.net/dotnetdesigner/archive/2007/11/08/1874605.aspxThe Collection interfa
Java Collection Framework Summary (4) Use of the--list interfaceThe list collection represents an ordered collection, and each element in the collection has its corresponding sequential index. The list collection allows you to use duplicate elements, which can be indexed to access the collection elements at the specified location.1.
When you use Sina Weibo's API to do projects, you need to get a list of all the users who have forwarded a particular microblog. decided to use Statuses/repost_timeline to get a forwarding list, but found two problems:
1: Sina Weibo has limited access to this interface and can only return the latest 2000 data. The official document says: This
since the Redis cache is updated, each service implements the update function in the basic Rediscacheupdate interface, and in the scheduled task, it uses the List The > method calls update in bulk, but there are cache dependencies between the service, such as service B relying on service A's cache, so that if B is updated then it will not fetch the cached data and every time it is taken in the database, it

Collection sub-interface (List/Set/Queue/SortedSet), queuesortedsetMain sub-interfaces of Collection:
List: stores duplicate content.
Set: duplicate content cannot be stored. All duplicate content is differentiated by hashCode () and equals ().
Queue: Queue Interface
SortedSet: sorts data in a set.
