Join Alex Theedom for an in-depth discussion in this video Solution: Find the value of a JSON key, part of JSON Processing with Java EE.
(light, inquisitive music)…- [Instructor] So, how did you get on…with your first streaming model challenge?…Here's how I solved it.…As you can see, all I do is to create a parser…by passing it the JSON data I want to search,…and iterate over the events generated by the parser.…I filter on the key_name event,…test the key_name against the key provided,…and only return a value if it is a string or a number.…Otherwise, I return null.…A more sophisticated example might also return arrays…and objects as strings, but I'll leave that up to you to do.…
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.
