Retrieve the last entry in the TreeMap in Java

Use the lastEntry() method in TreeMap to retrieve the last entry.

Create a TreeMap and add some elements −

TreeMap<Integer,String> m = new TreeMap<Integer,String>();
m.put(1,"India");
m.put(2,"US");
m.put(3,"Australia");
m.put(4,"Netherlands");
m.put(5,"Canada");

Now, retrieve the last entry −

m.lastEntry()

The following is an example to retrieve last entry in the TreeMap −

Example

 Live Demo

import java.util.*;
public class Demo {
   public static void main(String args[]) {
      TreeMap<Integer,String> m = new TreeMap<Integer,String>();
      m.put(1,"India");
      m.put(2,"US");
      m.put(3,"Australia");
      m.put(4,"Netherlands");
      m.put(5,"Canada");
      for(Map.Entry e:m.entrySet()) {
         System.out.println(e.getKey()+" "+e.getValue());
      }
      System.out.println("Last Entry in Map is "+m.lastEntry());
   }
}

Output

1 India
