Iterate LinkedList in reverse order

In the previous post, we have learnt about LinkedList ListIterator. In this post, we will learn how to iterate LinkedList in reverse order.

There is a methodĀ descendingIterator() to iterate over a list in reverse order.

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

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.descendingIterator();
		System.out.println("Iterate list in reverse order");
		while(iter.hasNext()){
			System.out.println(iter.next());
		}

	}
}

Output:

Iterate list in reverse order
Dates
Grapes
Banana
Mango
Grapes
Apple
Mango
Orange
