How is gson used to serialize json files?


Asked by Madalynn Short on Dec 04, 2021 JSON



The JSON filename extension is .json. JSON is directly consumable by JavaScript. Gson is a Java serialization/deserialization library to convert Java Objects into JSON and back. Gson was created by Google for internal use and later open sourced.
Accordingly,
Serialization in the context of Gson means converting a Java object to its JSON representation. In order to do the serialization, we need a Gson object, which handles the conversion. Next, we need to call the function toJson () and pass the Employee object. Gson toJson () Example
Indeed, JSON is a format that encodes objects in a string. Serialization means to convert an object into that string, and deserialization is its inverse operation. When transmitting data or storing them in a file, the data are required to be byte strings, but complex objects are seldom in this format.
Subsequently,
We'll use the toJson (Object src, Appendable writer) method from the Gson class to convert a Java data type into JSON and store it in a file. The Gson () constructor creates a Gson object with default configuration: Now, we can call toJson () to convert and store Java objects.
Next,
Serialization is the process of encoding the from naive datat type to JSON format. The Python module json converts a Python dictionary object into JSON object, and list and tuple are converted into JSON array, and int and float converted as JSON number, None converted as JSON null.
