本文整理了Java中org.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.json.JSONObject
类名称：JSONObject
方法名：optJSONArray

JSONObject.optJSONArray介绍

[英]Returns the value mapped by name if it exists and is a JSONArray. Returns null otherwise.
[中]返回按名称映射的值（如果该值存在且为JSONArray）。否则返回null。
