Convert String to JsonObject

Using JsonParser

The first approach we’ll see for converting a JSON String to a JsonObject is a two-step process that uses the JsonParser class.

  1. we need to parse our original String.
  2. Once we have our String parsed in a JsonElement tree, we’ll use the getAsJsonObject() method, which will return the desired result.

Gson provides us a parser called JsonParser, which parses the specified JSON String into a parse tree of JsonElements:

public JsonElement parse(String json) throws JsonSyntaxException

Using fromJson

In our second approach, we’ll see how to create a Gson instance and use the fromJson method. This method deserializes the specified JSON String into an object of the specified class:

public <T> T fromJson(String json, Class<T> classOfT) throws JsonSyntaxException
