本文整理了Java中javax.json.Json类的一些代码示例，展示了Json类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Json类的具体详情如下：
包路径：javax.json.Json
类名称：Json

Json介绍

[英]Factory class for creating JSON processing objects. This class provides the most commonly used methods for creating these objects and their corresponding factories. The factory classes provide all the various ways to create these objects.

The methods in this class locate a provider instance using the method JsonProvider#provider(). This class uses the provider instance to create JSON processing objects.

The following example shows how to create a JSON parser to parse an empty array:

StringReader reader = new StringReader("[]"); 
JsonParser parser = Json.createParser(reader);

All the methods in this class are safe for use by multiple concurrent threads.
[中]用于创建JSON处理对象的工厂类。此类提供了创建这些对象及其相应工厂的最常用方法。工厂类提供了创建这些对象的各种方法。
此类中的方法使用方法JsonProvider#provider（）定位提供程序实例。此类使用提供程序实例创建JSON处理对象。
以下示例显示如何创建JSON解析器来解析空数组：

StringReader reader = new StringReader("[]"); 
JsonParser parser = Json.createParser(reader);

此类中的所有方法对于多个并发线程都是安全的。

  JsonArray arr  = obj.getJsonArray(o);
  for(JsonValue v: arr)
   seedWords.get(o).add(CandidatePhrase.createOrGet(v.toString()));
 }
 return seedWords;
