    Yes, you’ll want to use the Jackson library’s ObjectMapper class for that.

private static final ObjectMapper OBJECT_MAPPER = new ObjectMapper();
private static final TypeReference<Object> TYPE_REF = new TypeReference<Object>() {};
...
Object parsedResponse = OBJECT_MAPPER.readValue(response, TYPE_REF);

    Hope that helps.
