包路径：com.google.common.collect.Multiset
类名称：Multiset
方法名：add

Multiset.add介绍

[英]Adds a single occurrence of the specified element to this multiset.

This method refines Collection#add, which only ensures the presence of the element, to further specify that a successful call must always increment the count of the element, and the overall size of the collection, by one.
[中]将指定元素的单个匹配项添加到此多集。
此方法细化了Collection#add，它只确保元素的存在，进一步指定成功的调用必须始终将元素的计数和集合的总体大小增加1。
