# JSON

## Overview

Json is a way to structure data quickly and with good readability and has a key/data structure very similar to the java hasmap or the python dictionary.

## How to use

the two ways to use JSON in TotalCross:

### Beans

You need to create the data beans that will be received in JSON

```java
//Where the data parameter is a variable that contains the JSON
Response response = JSONFactory.parse(data, Response.class);
```

You can see more abount this in [REST API](https://app.gitbook.com/@totalcross/s/playbook/apis/api-rest)

### JSON Object

```java
//Where the data parameter is a variable that contains the JSON
JSONObject jsonObject = new JSONObject(data);
```

You can use the variable jsonObject  like a hashmap.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://learn.totalcross.com/documentation/apis/json.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
