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

AbstractCharSequenceAssert.isEmpty介绍

[英]Verifies that the actual CharSequence is empty, i.e., it has a length of 0 and is not null.

If you want to accept a null value as well as a 0 length, use org.assertj.core.api.AbstractCharSequenceAssert#isNullOrEmpty() instead.

This assertion will succeed:

String emptyString = "" 
assertThat(emptyString).isEmpty();

Whereas these assertions will fail:

String nullString = null; 
assertThat(nullString).isEmpty(); 
assertThat("a").isEmpty(); 
assertThat("   ").isEmpty();

[中]验证实际CharSequence是否为空，即其长度为0且不为null。
如果希望接受空值和0长度，请使用org。资产j。果心应用程序编程接口。AbstractCharSequenceAssert#改为isNullOrEmpty（）。
此断言将成功：

String emptyString = "" 
assertThat(emptyString).isEmpty();

而这些断言将失败：

String nullString = null; 
assertThat(nullString).isEmpty(); 
assertThat("a").isEmpty(); 
assertThat("   ").isEmpty();
