类的具体详情如下:
包路径:java.util.SortedSet
类名称:SortedSet
[英]SortedSet is a Set which iterates over its elements in a sorted order. The order is determined either by the elements natural ordering, or by a Comparator which is passed into a concrete implementation at construction time. All elements in this set must be mutually comparable. The ordering in this set must be consistent with equals of its elements.
[中]SortedSet是按排序顺序在其元素上迭代的集合。顺序由元素的自然顺序决定,或者由在构建时传递到具体实现中的比较器决定。此集合中的所有元素必须相互可比。这个集合中的顺序必须与其元素的等号一致。

private static <E extends Comparable<? super E>> SortedSet<E> nullCheckedTreeSet(E[] elements) {
SortedSet<E> set = newTreeSet();
for (E element : elements) {
// Explicit null check because TreeSet wrongly accepts add(null) when empty.
set.add(checkNotNull(element));
}
return set;
}
