The default behaviour that is implemented in Gson is that null object fields are ignored. This allows for a more compact output format; however, the client must define a default value for these fields as the JSON format is converted back into its Java form.

It prepares an in-memory tree representation of the JSON document. It builds a tree of JsonObject nodes. It is a flexible approach and is analogous to DOM parser for XML. It converts JSON to and from POJO (Plain Old Java Object) using property ...

May 29, 2022 - GSON - Serialize and Deserialize Primitives Types - In this quick article, we will discuss how to use GSON to serialize or deserialize any primitive type into JSON representation. Convert Java Object to JSON using GSON - In this article, we will create an example of converting or serializing Java objects to JSON representation using the GSON library.

When using an existing {@code JsonReader}, manually apply the reader settings of this * {@code Gson} instance listed by {@link #newJsonReader(Reader)}. * Otherwise, when not using an existing {@code JsonReader}, use {@link * #newJsonReader(Reader)} to construct one. * ... Call {@link JsonReader#peek()} and verify that the result is {@link JsonToken#END_DOCUMENT} * to make sure there is no trailing data * * * Note that the {@code JsonReader} created this way is only 'legacy strict', it mostly adheres to * the JSON specification but allows small deviations.
