本文整理了Java中com.google.common.collect.Maps.immutableEntry()方法的一些代码示例，展示了Maps.immutableEntry()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。Maps.immutableEntry()方法的具体详情如下：
包路径：com.google.common.collect.Maps
类名称：Maps
方法名：immutableEntry

Maps.immutableEntry介绍

[英]Returns an immutable map entry with the specified key and value. The Entry#setValue operation throws an UnsupportedOperationException.

The returned entry is serializable.
[中]返回具有指定键和值的不可变映射项。条目#setValue操作抛出一个不支持的操作Exception。
返回的条目是可序列化的。
