Java Example Programs – Read All Elements in Vector Using Iterator

Hello, in this post we will see a java example program. We will learn how to read all elements in vector using an iterator.

WHAT IS AN ITERATOR ?
in Java, Iterator is an interface that available in collection framework in java.util.package. It’s a java cursor to iterate a collection of object.
Iterator<E> iterator()
Returns an iterator over the elements in this list in proper sequence.

Here you go

package com.practice.house;

import java.util.Iterator;
import java.util.Vector;

/**
 *
 * @author marifurr
 */
public class JavaVector {

    public static void main(String[] args) {

        Vector<String> vct = new Vector<String>();
        //adding elements
        vct.add("First");
        vct.add("Second");
        vct.add("Third");
        vct.add("Random");

        //Iterator<E> iterator()
        //Returns an iterator over the elements in this list in proper sequence.
        
        Iterator<String> itr = vct.iterator();
        while (itr.hasNext()) {
            System.out.println(itr.next());
        }
    }
}

package com.practice.house;

import java.util.Iterator;

import java.util.Vector;

/**

* @author marifurr

public class JavaVector {

public static void main(String[] args) {

Vector<String> vct = new Vector<String>();

//adding elements

vct.add("First");

vct.add("Second");

vct.add("Third");

vct.add("Random");

//Iterator<E> iterator()

//Returns an iterator over the elements in this list in proper sequence.

Iterator<String> itr = vct.iterator();

while (itr.hasNext()) {

System.out.println(itr.next());

}
