本文整理了Java中java.lang.Enum.toString()方法的一些代码示例，展示了Enum.toString()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。Enum.toString()方法的具体详情如下：
包路径：java.lang.Enum
类名称：Enum
方法名：toString

Enum.toString介绍

[英]Returns a string containing a concise, human-readable description of this object. In this case, the enum constant's name is returned.
[中]返回一个字符串，其中包含此对象的简明易读描述。在本例中，将返回枚举常量的名称。
