LinkedList Iterator in java

In the previous post, we have seen how to get the sublist from LinkedList. In this post, we will learn about LinkedList Iterator in java.

After creating a LinkedList Iterator, we call method Iterator() to get Iterator interface.

It has 2 methods.

hasnext(): I verifies if Iterator has more elements

next(): It gets the next element present in the list.

Example:

import java.util.Iterator;
import java.util.LinkedList;
import java.util.List;

public class LinkedListEx {

	public static void main(String[] args) {
		LinkedList<String> fruits = new LinkedList<String>();
		fruits.add("Orange");
		fruits.add("Mango");
		fruits.add("Apple");
		fruits.add("Grapes");
		fruits.add("Mango");
		fruits.add("Banana");
		fruits.add("Grapes");
		fruits.add("Dates");
		
		Iterator iter= fruits.iterator();
		while(iter.hasNext()){
			System.out.println(iter.next());
		}

	}
}

Output:

Orange
Mango
Apple
Grapes
Mango
Banana
Grapes
Dates
