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.
