本文整理了Java中org.apache.directory.api.util.Strings.isEmpty()方法的一些代码示例，展示了Strings.isEmpty()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。Strings.isEmpty()方法的具体详情如下：
包路径：org.apache.directory.api.util.Strings
类名称：Strings
方法名：isEmpty

Strings.isEmpty介绍

[英]Checks if a String is empty ("") or null.

StringUtils.isEmpty(null)      = true 
StringUtils.isEmpty("")        = true 
StringUtils.isEmpty(" ")       = false 
StringUtils.isEmpty("bob")     = false 
StringUtils.isEmpty("  bob  ") = false

NOTE: This method changed in Lang version 2.0. It no longer trims the String. That functionality is available in isBlank().
[中]检查字符串是否为空（“”）或null。

StringUtils.isEmpty(null)      = true 
StringUtils.isEmpty("")        = true 
StringUtils.isEmpty(" ")       = false 
StringUtils.isEmpty("bob")     = false 
StringUtils.isEmpty("  bob  ") = false

注意：在Lang 2.0版中，此方法发生了更改。它不再修剪绳子。该功能在isBlank（）中可用。
