TreeSet.headSet介绍

[英]Returns a SortedSet of the specified portion of this TreeSet which contains elements less than the end element. The returned SortedSet is backed by this TreeSet so changes to one are reflected by the other.
[中]返回此树集的指定部分的SortedSet，其中包含的元素少于end元素。返回的SortedSet由该树集支持，因此对其中一个树集的更改由另一个树集反映。
