Join Alex Theedom for an in-depth discussion in this video Challenge: Find the value of a JSON key, part of JSON Processing with Java EE.
(chiming music)…- [Instructor] This is your first challenge…in the string of the chapter and it is to write…the method that traverses a JSON document…and retrieves a value of a given key.…You should be able to call a method retrieveValue…and parser the key name and a JSON string to parse.…To make it simple, let's just make it return a value.…If the key's value is a string or a number,…we don't need to write logic that returns an array…or an object.…And don't forget, write the appropriate unit tests.…The estimated completion time for this task…is about 20 minutes.…
In this course, discover how to use the Java Enterprise Edition (EE) JSON-Processing API. With its two programming models, JSON-Processing is one of the simplest ways to generate, query, and parse JSON data, and you'll find that implementing it in your projects is quick and easy. Join Alex Theedom as he covers an array of topics, including how to use both the object model and the streaming model, how to traverse a JSON structure, and how to parse JSON data using the extensive builder APIs. When you wrap up this course, you'll be ready to develop with this essential and powerful API.
