本文整理了Java中org.apache.commons.collections.CollectionUtils.isNotEmpty()方法的一些代码示例，展示了CollectionUtils.isNotEmpty()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。CollectionUtils.isNotEmpty()方法的具体详情如下：
包路径：org.apache.commons.collections.CollectionUtils
类名称：CollectionUtils
方法名：isNotEmpty

CollectionUtils.isNotEmpty介绍

[英]Null-safe check if the specified collection is not empty.

Null returns false.
[中]如果指定的集合不为空，则执行Null安全检查。
Null返回false。
