, and Org.json can not directly with the bean conversion and need map as a transit, if the bean to JSON data, first need to convert the bean to M The AP then turns the map into JSON, which is more cumbersome.In short, or that sentence-suitable for their own is the best, we need to choose which method to use to resolve. Finally, we introduce two tools for parsing JSON
JSON string to Java object There are a lot of tools to use, the following small example is just my practicing
Copy Code code as follows:
Import java.util.ArrayList;
Import Java.util.HashMap;
Import java.util.List;
Import Java.util.Map;

public static void Main (string[] args) {Object O1 = Parse ("{\" aa\ ": 123,cc:[1,2,3,4,{
With the use of third-party APIs, sometimes JSON data is obtained from the network, so how will we parse the JSON data?

A lot of JSON constructs and parsing tools are published on www.json.org, in which Org.json and json-lib are relatively simple, but there are some differences in the use of the two. The following is an example of how to construct and parse JSON data using Org.json.First, IntroductionThe Org.json package is another package used to Beans,collections,maps,

Foundation Beddingin Java, there are a lot of lib for JSON, such as Jackjson, Fastjson, Gson, and so on, which I've used, but it's too onerous for programmers like me who just want the Java object to return to the JSON string. And some features are very poor customization, such as a
JSON is a very concise and important data format that is commonly used to exchange data, widely used in JavaScript technology, and is increasingly being fired up in a variety of popular programming languages. There is also a library of JSON in Java that is important to use for the interaction of Java objects with

1. Introduction:
XML: extensible markup language, a language similar to HTML. It has no predefined tags and uses document type definition (DTD) to organize data. The format is uniform, cross-platform and language have long been recognized in the industry. For details, refer to Google or Baidu. Compared with JSON, a lightweight data exchange format, XML can be called heavyweight.
