Number of JSON object can vary. I tried to generate POJO from jsonschema2pojo but it generate fix number of object inside AvailableDeliveries class. How I can define a POJO with collection of object and map corresponding field for above JSON string. I can't change the structure of JSON response as I am consuming the string.
I looked on other examples which have collection of object but I have this extra top level object "AvailableDeliveries" not sure how to handle that level.
I must write a method that accepts a string and returns an int. The method should sum the unicode values of each character, so the string "ABC" should return 198. Also the only string class methods I'm aloud to use are length, charAt, and substring. I just don't know how the get the Unicode value.

So I would like to get information out of a web-API. But my question is how I do this. I guess I need to read the URL first. And parse it after but what is the best way?
I would like some clarification on a project I am working on. I need to build a java application to query a xml and json file. I have started by parsing both documents and I am unsure if I am doing the next steps correct. I was thinking about dropping the txt file with both outcomes into a db and doing it that way, is this the right way or is there a better and more efficient way of doing things ?
I want to pass the current timestamp as a key-value pair in JSON and want to store that timestamp in my DynamoDB table. Any sample code in JAVA to perform this operation.
I'm new to json and the web. My purpose is to use json data from a server and parse it and show meaningful data to the user. I am aware of json parsing, so no sweat there. However, I would like to know how json data is sent to the front end after which it can be parsed.
Usually in my json parsing examples, I have a variable like var data = ]OR I do a getJSON on a data.json file which I have stored in the project folder. However, I want this data to come real time from a servlet. How to go about this?
So, basically my question is, how do I send real time json data from a servlet backend, say some records which I have extracted from the database using jdbc?

I'm trying to retrieve information from a json repository stored online. I have so far setup my code to create the string that could be used as the url. What I'm not sure about is how you setup a Json Parser?
- Would you recommend I use a library? I hear google-gson is meant to be good?
- How easy is it to convert a string into a URL? I assumed that this would be good enough
