本文整理了Java中org.codehaus.jettison.json.JSONObject.optJSONArray()方法的一些代码示例，展示了JSONObject.optJSONArray()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。JSONObject.optJSONArray()方法的具体详情如下：
包路径：org.codehaus.jettison.json.JSONObject
类名称：JSONObject
方法名：optJSONArray

JSONObject.optJSONArray介绍

[英]Get an optional JSONArray associated with a key. It returns null if there is no such key, or if its value is not a JSONArray.
[中]获取与键关联的可选JSONArray。如果没有这样的键，或者其值不是JSONArray，则返回null。
