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 statement

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.

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.
