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

JSONArray.optJSONObject介绍

[英]Get the optional JSONObject associated with an index. Null is returned if the key is not found, or null if the index has no value, or if the value is not a JSONObject.
[中]获取与索引关联的可选JSONObject。如果找不到键，则返回Null；如果索引没有值，或该值不是JSONObject，则返回Null。
