Interpret the source code of the JSON P default in the Java class library (Interpreting the Source Code of the DEFAULT PROVIDER of JSON P In Java Class Libraries)

In order to explain the source code of the JSON P default provided by JSON P in the Java library, we first need to understand what JSON P is.JSON P, full known as JSON PROCESSING (JSON processing), is a new set of APIs in Java Ee 7 for processing, reading, writing, and modifying the creation, reading, writing, and modification of JSON data. JSON P includes two core APIs: JSON Object API and JSON POINTER API.Among them, the JSON Object API provides a method for creating and operating the JSON object, and the JSON Pointer API is used to locate specific attributes or elements in the JSON object. JSON P's default procedure is a implementation of the JSON P specification, which provides developers with the default JSON processing function.We will analyze the source code of the JSON P default and related configuration. By reading the source code of the program provided by JSON P's default, you can understand the basic implementation principles and internal logic of JSON P.This helps us understand its working method when using JSON P and can be customized according to actual needs. Before interpreting the source code of JSON P's default program, you need to learn about the basic concepts and terms of some JSON P: 1. JSON Object: A set of key value pairs surrounded by large brackets {} indicate a disorderly set.The key value of the key value is a string, and the value can be any JSON type. 2. JSON array (JSON Array): A set of values surrounded by Fang parentheses [] indicate an orderly collection.Value can be any JSON type, including JSON objects and JSON array. 3. JSON Property: The key value in the JSON object is symmetrical as the attribute.The attribute consists of the attribute name (key) and the attribute value (value). 4. JSON Element: The value in the JSON array is called element. The source code of JSON P's default provided program can be divided into the following aspects for interpretation: 1. The creation and operation of the JSON object: The source code will include the method of creating the JSON object, such as "CreateObjectBuilder ()" and "ADD ()".These methods allow us to create and modify the JSON objects according to specific needs. 2. The creation and operation of the JSON array: The source code will include the method of creating the JSON array, such as "CreateArrayBuilder ()" and "Add ()".These methods allow us to create and modify the JSON array according to specific needs. 3. JSON attribute acquisition and modification: The source code will include methods to obtain and modify the JSON object attributes, such as "Get ()" and "Put ()". 4. Getting and modification of JSON elements: The source code will include methods to obtain and modify the JSON array elements, such as "get ()" and "set ()". By studying the source code, we can deeply understand the various functions of JSON P and make flexible adjustments according to our own needs. We need to configure related configurations before using the JSON P default.First of all, the JSON P library needs to be introduced into the project in order to use the JSON P -related class and methods in the code.Secondly, we can customize the configuration of JSON P according to need, such as modifying the default JSON processor, registering custom JSON processors, etc. To sum up, interpret the source code of the JSON P's default provision of the JSON P in the Java library includes the following steps: understanding the basic concepts and terms of JSON P, the creation and operation methods of the JSON object and the JSON array in the source code, the JSON attributes and research code in the source codeThe acquisition and modification methods of JSON elements, related configuration and customization.Through these steps, we can better use and understand JSON P, the source code of the program default.
