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

Multiset.contains介绍

[英]Determines whether this multiset contains the specified element.

This method refines Collection#contains to further specify that it may not throw an exception in response to element being null or of the wrong type.
[中]确定此多重集是否包含指定的元素。
此方法细化了集合#contains，以进一步指定它可能不会在元素为null或类型错误时引发异常。
