With Gson, we can easily transform the data objects and JSON objects, where we use two methods, one is Fromjson (), we convert the JSON object to the data object we need, and the other is Tojson (), This is the conversion of our data objects into JSON objects. Let's look at a comprehensive example of how Gson is used:
There are now a lot of JSON-related Java tools, such as Json-lib, Gson, and so on, which can convert javabean directly into JSON format.In development, it is possible to get data from the database and want to go directly to the JSON array, not through the bean.For
