Java program to sort the elements of a Vector collection

Given a Vector collection, we have to sort the elements.
Submitted by Nidhi, on May 26, 2022

Problem statement

In this program, we will create a Vector collection with integer elements. Then we will sort the elements of vector collection using the Collections.sort() method.

Source Code

The source code to sort the elements of a Vector collection is given below. The given program is compiled and executed successfully.

// Java program to sort the elements of a 
// Vector collection

import java.util.*;

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

    vec.add(10);
    vec.add(20);
    vec.add(30);
    vec.add(20);
    vec.add(12);

    System.out.println("Vector elements: " + vec);

    Collections.sort(vec);

    System.out.println("Sorted Vector: " + vec);
  }
}

Output

Vector elements: [10, 20, 30, 20, 12]
Sorted Vector: [10, 12, 20, 20, 30]

Explanation

In the above program, we imported the "java.util.*" package to use the Vector 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 Vector collection vec with integer elements. Then we used the Collections.sort() method to sort the elements of the Vector collection. After that, we printed the updated Vector collection.
