本文整理了Java中java.util.SortedSet.subSet()方法的一些代码示例，展示了SortedSet.subSet()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。SortedSet.subSet()方法的具体详情如下：
包路径：java.util.SortedSet
类名称：SortedSet
方法名：subSet

SortedSet.subSet介绍

[英]Returns a SortedSet of the specified portion of this SortedSet which contains elements greater or equal to the start element but less than the end element. The returned SortedSet is backed by this SortedMap so changes to one set are reflected by the other.
[中]返回此SortedSet指定部分的SortedSet，其中包含大于或等于起始元素但小于结束元素的元素。返回的SortedSet由该SortedMap支持，因此对一个集合的更改由另一个集合反映。

/** Calls the smallest subSet overload that filters out the extreme values. */
SortedSet<E> createSubSet(SortedSet<E> set, E firstExclusive, E lastExclusive) {
 if (from == Bound.NO_BOUND && to == Bound.EXCLUSIVE) {
  return set.headSet(lastExclusive);
 } else if (from == Bound.INCLUSIVE && to == Bound.NO_BOUND) {
  return set.tailSet(firstInclusive);
 } else if (from == Bound.INCLUSIVE && to == Bound.EXCLUSIVE) {
  return set.subSet(firstInclusive, lastExclusive);
 } else {
  throw new IllegalArgumentException();
 }
}
