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

AbstractMapAssert.isEmpty介绍

[英]Verifies that the Map is empty.

Example:

// assertion will pass 
assertThat(new HashMap()).isEmpty(); 
// assertion will fail 
Map<String, String> map = new HashMap(); 
map.put("key", "value"); 
assertThat(map).isEmpty();

[中]验证映射是否为空。
例子：

// assertion will pass 
assertThat(new HashMap()).isEmpty(); 
// assertion will fail 
Map<String, String> map = new HashMap(); 
map.put("key", "value"); 
assertThat(map).isEmpty();
