Streaming Large JSON Response in Spring.
To put things simply, this method findAllStreaming() takes an OutputStream to write the whole json response into. To write json into the stream chunk by chunk we are using JsonGenerator. JsonGenerator is provided by Jackson-Core. More detailed about how to write stream event is covered in this blog post by the author of the library.

Ryū: fast float-to-string conversion (Java lib, 2018 paper)
Jackson already has some improvements for string-to-number conversion over stock JDK parser (https://github.com/FasterXML/jackson-core/pull/677). Would be great if they added faster number-to-string too.

Data API for Amazon Aurora Serverless v2 with AWS SDK for Java - Part 3 Executing update and insert SQL statements in batch
In this concrete example we'll create 3 products. We can then convert this JSON to the list of products using Gson.

The Newest Java Json Benchmark Results just dropped
Gson has been in maintenance mode for at least 6 years. It's kind of a shame, because the API and implementation were a lot cleaner than Jackson.

How We Built a Serverless Backend Using GraalVM, AWS Lambda and Astra DB (Part 2)
For more information on native-image build arguments, please consult the GraalVM Native Image Options documentation. The next listing contains the contents of reflect.json, which contains a bunch of data classes that we need to serialize and deserialize with Gson, as well as our Lambda handler class which the runtime needs to instantiate based on the qualified class name passed to the Lambda function.

How to Make Java MRZ Detector with Dynamsoft Label Recognizer for Windows and Linux
The loadModel() method is special. It needs to dynamically update the model path specified in the JSON-formatted template file according to the extraction path of the Jar package. Gson can be used to load and update the JSON object.

Need help with planning a GUI project for my finals
However, I do know that there isn't an inbuilt JSON parser within Java. So, you will need to include a third-party JSON parser library within your project. I've had experience with using gson for doing this myself, and that library is also rather easy to use.
What are some alternatives?
When comparing Jackson and Gson you can also consider the following projects:
Moshi - A modern JSON library for Kotlin and Java.
jsoniter - jsoniter (json-iterator) is fast and flexible JSON parser available in Java and Go
Yasson - Eclipse Yasson project
Jackson JSON Processor - Main Portal page for the Jackson project
Genson - Genson a fast & modular Java <> Json library
kotlinx.serialization - Kotlin multiplatform / multi-format serialization
HikariJSON - High-performance JSON parser
LoganSquare - Screaming fast JSON parsing and serialization library for Android.
