Java program to convert a Vector collection into an Object array

Given a Vector collection, we have to convert a it into an Object array.
Submitted by Nidhi, on May 26, 2022

Problem Solution:

In this program, we will create a Vector collection with integer elements. Then we will convert created vector collection into an Object array using the toArray() method.

Program/Source Code:

The source code to convert a Vector collection into an Object array is given below. The given program is compiled and executed successfully.

// Java program to convert Vector collection 
// into an Object array

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);
    vec.add(40);
    vec.add(60);

    Object[] arr = vec.toArray();

    System.out.println("Vector collection: \n" + vec);

    System.out.println("\nArray elements: ");
    for (Object item: arr) {
      System.out.print(item + " ");
    }
  }
}

Output:

Vector collection: 
[10, 20, 30, 20, 12, 40, 60]

Array elements: 
10 20 30 20 12 40 60

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 converted Vector vec into an object array using the toArray() method. After that, we printed the Vector collection and object array.
