In order to use the functionalities of theSortedSetinterface, we need to use theTreeSetclass that implements it. How to use SortedSet? To useSortedSet, we must import thejava.util.SortedSetpackage first. // SortedSet implementation by TreeSet classSortedSet<String> animals =newTreeSet<>();...
Methods inherited from interface java.lang.Iterable forEach headSet SortedSet<E> headSet(EtoElement) Returns a view of the portion of this set whose elements are strictly less thantoElement. The returned set is backed by this set, so changes in the returned set are reflected in this set, an...
This interface is a member of theJava Collections Framework. Added in 1.2. Java documentation forjava.util.SortedSet.

TheSortedSetinterface contains operations to return the first and last elements in the sorted set, not surprisingly calledfirstandlast. In addition to their obvious uses,lastallows a workaround for a deficiency in theSortedSetinterface. One thing you'd like to do with aSortedSetis to go into ...

Java中的SortedSet first()方法SortedSet接口中的first()方法用于返回集合中第一个即最低的元素。 语法: :E first() Java Copy其中,E是此集合维护的元素类型。 参数: :此函数不接受任何参数。 返回值: :它返回集合中当前第一个或最低的元素。 异常: :如果集合为空,则抛出 NoSuchElementException。 下面的...
