Today, I would like to share with you the relevant knowledge of what the common data structure of java is. The content is detailed and the logic is clear. I believe most people still know too much about this, so share this article for your reference. I hope you can get something after reading this article. Let's take a look.

The operating environment of this tutorial: windows7 system, java10 version, DELL G3 computer.

1. Concept

It is the way in which computers store and organize data, which refers to a collection of one or more specific relationships between data elements.

2. Function

(1) insert a new data item

(2) looking for a specific data item

(3) Delete a specific data item

(3) iteratively access each data item for display or other operations

3. Common data structures

(1) Linear table

The most commonly used and simplest data structure, which is a finite sequence of n data elements,

Realize linear table: output and store linear table elements, that is, use a set of continuous storage units to store linear table data elements in turn, and the other is to use linked lists to store linear table elements. use a set of arbitrary storage units to store the data elements of a linear table (storage units can be continuous or discontinuous).

(2) Stack

First in and then out

(3) queue

Add elements in a paragraph. The other end takes out the element. Get in and out of the team. Usage scenario: because of the first-in-first-out nature of the queue, it is very suitable for multithreaded blocking queue management.

(4) linked list

A discontinuous, non-sequential storage structure on a physical storage unit. The logical order of data elements is realized by the pointer address of the linked list. Each element contains two nodes, one is the data field (storage space) of the storage element, and the other is the pointer domain that points to the next node.

(5) Tree

A data structure consisting of a hierarchical set of n (n > = 1) finite nodes.

These are all the contents of the article "what are the common data structures in java?" Thank you for reading! I believe you will gain a lot after reading this article.
