In this article we will show you the solution of how to iterate list in java, the List interface in Java belongs to the Collection framework. Java makes extensive use of ArrayLists and LinkedLists.

Iterators are the easiest method for accomplishing these object implementing this interface implement either Iterator or ListIterator.

An iterator allows you to retrieve and remove elements from collections. Using ListIterator, a list can be traversed bidirectionally, and elements can be modified.

Iterators must be obtained before they can be used to access collections.

An iterator() method resides in each collection class and returns an iterator back to the collection's start. Iterators provide access to elements one at a time, allowing you to access each element separately.

We will now discuss the idea of how to iterate list in java with an example.

Step By Step Guide On How To Iterate List In Java :-

import java.util.*;
public class talkerscode
{
public static void main(string args[])
{
List<string> name = Arrays.aslist("Harry", "Amruta", "Ron", "Draco", "Hermineo", "Nevil");
ListIterator<string> listIterator = name.listIterator();
while(listIterator.hasNext())
{
System.out.println(listIterator.next());
}
}
}

1. In our example, we import the java.util package, which contains utility classes such as the List interface, the Arrays class, and the ListIterator interface.
2. There is a class named 'talkerscode' that we define.
3. As part of the initialization procedure, the main() method is declared as the program's entry point.
4. We define the list 'name' using the Arrays.asList() method within the main() method. A fixed-size list backed by an array is returned by this method, which takes a variable number of arguments.
5. Our ListIterator is initialized with a name by defying the listIterator() method and declaring a String named 'listIterator'.
6. With the help of the hasNext() and next() methods of the ListIterator interface, we iterate through the list in a while loop.
7. By using the println() method of the System class, we are able to print out the elements of the list.
8. Once the program has finished iterating over all the elements, it terminates.

Conclusion :-

As a result, we have successfully learned how to iterate list in java with an example.

There are several methods you can use to iterate over a list in Java, such as "for loops", "while loops", iterators, and more.

You can achieve this by defining an array and adding items to it using the constructor of the ArrayList class.

You can now display output on the console by using the "for" or "while" loop. An introduction to Java's iteration over lists was presented in this article.

I hope this article on how to iterate list in java helps you and the steps and method mentioned above are easy to follow and implement.
