Java - The SortedMap Interface The SortedMap interface extends Map. It ensures that the entries are maintained in ascending key order Several methods throw a NoSuchElementException when no items are in the invoking map. A ClassCastException is thrown when an object is incompatible with the elemen...
Uses of SortedMap in java.util.concurrent Subinterfaces of SortedMap in java.util.concurrent Modifier and Type Interface Description interface ConcurrentNavigableMap<K,V> A ConcurrentMap supporting NavigableMap operations, and recursively so for its navigable sub-maps.

The following idiom obtains a view containing all of the key-value mappings in m whose keys are between low and high, exclusive: SortedMap<String, V> sub = m.subMap(low+"\0", high); This interface is a member of the Java Collections Framework....

注意:SortedMap中的put()方法是从Java中的Map接口继承的。 以下示例程序旨在说明int put()方法的实现: 示例1: // Java code to show the implementation of // put method in SortedMap interface import java.util.*; public class GfG { // Driver code ...

public interface SortedMap<K,V> extends Map<K,V> 保证按照键的升序排列的映射,可以按照键的自然顺序(参见 Comparable 接口)进行排序, 或者通过创建有序映射时提供的比较器进行排序。对有序映射的集合视图 (由 entrySet、keySet 和 values 方法返回)进行迭代时,此顺序就会反映出来。

(This interface is the map analogue of {@link SortedSet}.) SortedMap提供key排序; SortedMap使用 元素key的Comparable自然排序 或 创建时的Comparator; 使用SortedMap的entrySet、keySet、values会返回已排序的内容; All keys inserted into a sorted map must implement the {@code Comparable} interface (or ...
