Use of JSON

JSON has recently been used extensively in the project, and it is found that JSON and XML are similar in functionality and are a data transfer format. JSON is more lightweight and easier to use than XML.

JSON-dependent third-party jar packages:

Commons-beanutils.jar
Commons-collection.jar
Commons-lang.jar
Commons-logging.jar
Ezmorph-1.0.6.jar
Json-lib-2.4-jdk15.jar

It concludes that there are three scenarios in which JSON strings are converted to Java objects in the following ways:

(1) Conversion between Java Bean object and JSON string

(2) conversion between Java arrays and JSON strings

(3) The conversion between Java list and JSON string

Here is a JSON tool Class I wrote:
