Java Collection, LinkedList Exercises: Exercise-16 with Solution

Write a Java program to shuffle the elements in a linked list.

Sample Solution:-

Java Code:

import java.util.*;

public class Exercise16 {
 public static void main(String[] args) {
  // create an empty linked list
  LinkedList <String> l_list = new LinkedList <String> ();
  // use add() method to add values in the linked list
  l_list.add("Red");
  l_list.add("Green");
  l_list.add("Black");
  l_list.add("Pink");
  l_list.add("orange");
  // print the list
  System.out.println("Linked list before shuffling:\n" + l_list);  
  Collections.shuffle(l_list);
  System.out.println("Linked list after shuffling:\n" + l_list); 
  }
}

Sample Output:

Linked list before shuffling:                                          
[Red, Green, Black, Pink, orange]                                      
Linked list after shuffling:                                           
[orange, Pink, Red, Black, Green]
