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。
