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. JSON: JavaScript Object Nota

Java's JSON open-source package can only parse JSON data, without arithmetic functions.

For example, when you write a JSON file condition filter in Java, you need to rewrite the c

JSON (JavaScript Object notation) is a lightweight data interchange format. Easy for people to read and write. It is also easy to machine parse and generate.

Operate data in JSON format in JAVA In recent days, the company has been engaged in projects, and some of the interfaces provided by official APIs need to be requested in POST mode, and the data transmission format must be in JSON format, I have never studied it before, and the transmitted data format is relatively simple. Therefore, it is directly assembled by
