QUESTION
I have a json file with multiple arrays. It is not clear to me how to set up Key-Value pairs when this isn't one given. I understand that a [ … ] represents an array and { … } represents an object. I looked at tutorials online but none had an answer to my question and what I found in this JSON.
The Problem: I'm trying to convert every property in the JSON to POJO / dataTypes. There are these properties in the arraylist below that don't have a key-value pair. "5", "1964-07-20", null, "7", null, Within this arraylist there are properties that have a key-value pair. { "retail": "7.05", "price": "12.07", "cost": "3.01", "fees": "1.75", "profit": "5.85" } How to create a class that handles both and stores each property to a datatype. It will have the same fields at the start (the 5 none key properties), It will always be the same. The Value is what only changes.
Thanks in advance.
There is no Key-Value associated with the below properties
...ANSWER
Answered 2021-Mar-08 at 16:24The main problem here seems to lie with your JSON format. It starts off fine with the artist, record etc. but then you have defined an array of musicRecords which seems to not only represent an array of records but also some extra data as well (a date "1964-07-20" for example).
Without knowing what this structure is for, it would seem like those fields belong with the artist and record fields in your root JSON object, where they need some sort of key to represent their purpose.
Then you could easily make a POJO that makes a bit more logical sense and will be easier to use in your project.
However if the JSON file is coming from an external source that you have no influence over, you have two options:
Use the JSON Auto Formatted File that you posted
This approach is probably not the best idea, mostly due to the POJO then not representing a logical object that will be easy to use in your code but also because of type safety. You have to upcast all of the objects in your list to Object which would mean casting them all back down again when they need to be accessed. This is generally bad practice and if the JSON structure changed at all this would be very difficult to debug.
Use a different JSON library
The best solution would be to use a JSON library that allows you to read a JSON file step by step and then map to a POJO that you're comfortable with and better represents your use case. However as far as I am aware, GSON is a direct deserialization library so cannot offer the fine tuning you would need to map to a different format.

So the link have to point to a Route in a Switch, as is in the example of the link.

QUESTION
I wonder what's the recommended way to generate POJOs for Json schemas with "anyOf" fields?
For example, given the following json schemas:
hobby.json ...ANSWER
Answered 2020-Aug-09 at 08:10I think there are two approaches that seem natural:
One would be to generate a class hierarchy Hobby with the common field timeSpent and Music / Exercise being subclasses with their specific fields.
The other would be to "union" the fields into a single class Hobby.
Both are semantically incorrect meaning that you can come up with cases where JSON schema validates correctly but Jackson throws an error or the information is missing in the POJO due to an omitted field.
So I think the best approach here would be to resort to Map instead of pojos.
So for example if a Person has a hobby the Person POJO could be:

I receive the following errors when trying to build my page using "Yarn Build"

Answered 2020-Apr-04 at 12:20Here is the simplified code. Keep the glob as is, it seems to be working fine. The issue is in how you parse the names from the list.
In this snippet you will see the issue of the blogSlugs from your code and the newBlogSlugs as a solution.
What the newBlogSlugs code does?
file.replace(/^.*[\\\/]/, '').split('.')[0]
Replace methods replaces all the path parts except the last one and we get "cupcakes.md". Then we split the string on the dot and use only the first part and get "cupcakes".

QUESTION
So, I'm making my own home assistant and I'm trying to make a multi-intent classification system. However, I cannot find a way to split the query said by the user into the multiple different intents in the query.
For example:
...ANSWER
Answered 2019-May-13 at 06:40It seems that you are mixing two problems in your questions:
- Multiple independent intents within a single query (e.g.
shut down the music and play White Collar) - Multiple slots (using the form-filling framework) within a single intent (e.g.
turn the lights off in the living room bedroom and kitchen).
These problems are quite different. Both, however, can be formulated as word tagging problem (similar to POS-tagging) and solved with machine learning (e.g. CRF or bi-LSTM over pretrained word embeddings, predicting label for each word).
The intent labels for each word can be created using BIO notation, e.g.

Program runs as it should until I try to use the function once again and it returns the error: Can't set headers after they are sent.
I'm creating this app to familiarize myself with nodejs and javascript and I've been reading about the error and it seems to be an issue when sending more than one response to a request. I started using res.setHeader before knowing this, but I read that res.header could avoid this problem, it didn't solve it but I kept it.

Answered 2019-Apr-09 at 20:46There are several problems with your current setup:
- Try not to use event emitter for signaling events within an HTTP request, it wasn't made for this.
- With HTTP requests, try not to use global variables for data received during the request, when two requests come in at the same time, they may get confused and get sent the wrong data.

I wasnt resolving a promise in each function, i only had a return. I changed the line where I have return json; to resolve(json);
