Java program to iterate Vector collection using the iterator() method

Given a Vector collection, we have to iterate it using the iterator() method.
Submitted by Nidhi, on May 23, 2022

Problem Solution:

In this program, we will create a Vector collection with string elements. Then we will access vector collection elements one by one using the iterator() method and print them.

Program/Source Code:

The source code to iterate Vector collection using the iterator() method is given below. The given program is compiled and executed successfully.

// Java program to iterate Vector collection 
// using the iterator() method

import java.util.*;

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

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

    Iterator itr = vec.iterator();
    System.out.println("Vector elements are: ");

    while (itr.hasNext()) {
      System.out.println(itr.next());
    }
  }
}

Output:

Vector elements are: 
CAR
BUS
BIKE
BUS
TRUCK

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 string elements. Then we used the iterator() method to access elements of the Vector collection one by one and printed them.
