java reverse treemap code example
Example 1: TreeMap descendingMap() method in java
import java.util.NavigableMap;
import java.util.TreeMap;
public class TreeMapDescendingMapMethodExample
{
public static void main(String[] args)
{
TreeMap<Integer, String> tm = new TreeMap<Integer, String>();
tm.put(93, "blue");
tm.put(26, "violet");
tm.put(63, "red");
tm.put(53, "green");
tm.put(96, "five");
// put values in NavigableMap
NavigableMap nm = tm.descendingMap();
System.out.println("TreeMap values using descendingMap() method: ");
System.out.println("NavigableMap values: " + nm);
}
}
Example 2: treemap in reverse order
Map<String, String> treemap =
new TreeMap<>(Collections.reverseOrder());
