Problem statement

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.

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.
