Get last value in Java TreeSet

To get the last value in TreeSet, use the last() method.

First, get the TreeSet and add elements to it −

TreeSet<String> tSet = new TreeSet<String>();
tSet.add("10");
tSet.add("20");
tSet.add("30");
tSet.add("40");
tSet.add("50");
tSet.add("60");

Now, get the first value −

tSet.last()

The following is an example to get the last value in TreeSet −

Example

 Live Demo

import java.util.*;
public class Demo {  
   public static void main(String args[]){
      TreeSet<String> tSet = new TreeSet<String>();
      tSet.add("10");
      tSet.add("20");
      tSet.add("30");
      tSet.add("40");
      tSet.add("50");
      tSet.add("60");
      System.out.println("TreeSet elements...");
      Iterator<String> i = tSet.iterator();
      while(i.hasNext()){
         System.out.println(i.next());
      }
      System.out.println("Last Value = " + tSet.last());
   }
}

Output

TreeSet elements...
10
20
30
40
50
60
Last Value = 60
