Sort elements of linkedlist in java (ascending & descending order)

• The LinkedList class extends AbstractSequentialList and implements the List interface.
• Given an LinkedList, we would like to sort elements of linkedlist in ascending and descending order.

Program – Sort linked list in ascending & descending order

package org.learn.collection.list.linkedlist;

import java.util.Collections;
import java.util.LinkedList;

public class SortElementInLinkedList {

	public static void main(String[] args) {
		LinkedList<String> LinkedList = new LinkedList<>();
		LinkedList.add("archery");
		LinkedList.add("golf");
		LinkedList.add("diving");
		
		System.out.println("Sort elements of arrayList: ");
		demoSortMethod(LinkedList);		
	}	

	private static void demoSortMethod(LinkedList<String> linkedList) {
		//[archery, golf, diving]
		System.out.println("Orignal LinkedList:" + linkedList);
		Collections.sort(linkedList);
		// [archery, diving, golf]
		System.out.println("1. Sort ascending order: " + linkedList);

		Collections.sort(linkedList, Collections.reverseOrder());
		// [golf, diving, archery]
		System.out.println("2. Sort desending order: " + linkedList);
	}	
}

Output – Sort linkedlist in ascending & descending order

Sort elements of arrayList: 
Orignal LinkedList:[archery, golf, diving]
1. Sort ascending order: [archery, diving, golf]
2. Sort desending order: [golf, diving, archery]
