Submitted by Nidhi, on June 06, 2022

Problem Solution:

In this program, we will create a TreeSet collection with integer elements. Then we will find the largest item from the TreeSet collection using the last() method.

Program/Source Code:

The source code to get the largest item from the TreeSet collection is given below. The given program is compiled and executed successfully.

Example of TreeSet.last() Method in Java

// Java program to get the largest item from 
// TreeSet collection

import java.io.*;
import java.util.*;

public class Main {
  public static void main(String args[]) {
    TreeSet < Integer > tree = new TreeSet < Integer > ();

    tree.add(30);
    tree.add(20);
    tree.add(25);
    tree.add(10);

    int large = tree.last();

    System.out.println("Largest item in TreeSet is: " + large);
  }
}

Output:

Largest item in TreeSet is: 30

Explanation:

In the above program, we imported the "java.util.*", "java.io.*" packages to use the TreeSet class. Here, we created a public class Main.

The Main class contains a main() method. The main() method is the entry point for the program. And, created a TreeSet collection tree and added integer elements using add() method. Then we found the largest item from the TreeSet collection using the last() method and printed the result.
