Submitted by Nidhi, on May 20, 2022

Problem statement

In this program, we will create a Vector collection with string elements. Then we will copy elements of the Vector collection into an array using the copyInto() method.

Source Code

The source code to copy elements of Vector collection into an array is given below. The given program is compiled and executed successfully.

// Java program to copy elements of Vector collection 
// into an array

import java.util.*;

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

    String vehicles[] = new String[5];

    vec.add("CAR");
    vec.add("BUS");
    vec.add("BIKE");
    vec.add("TRUCK");

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

    vec.copyInto(vehicles);

    System.out.println("Array elements: ");
    for (String v: vehicles)
      System.out.println(" " + v);
  }
}

Output

Vector elements: [CAR, BUS, BIKE, TRUCK]
Array elements: 
 CAR
 BUS
 BIKE
 TRUCK
 null

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 and add elements to it. Then we create an array of strings. After that, we copied the elements of vector collection into a string array using the copyInto() method. After that, we printed the elements of the array.
