Shuffle elements in linked list in java

by

We can use Collections.shuffle() method to shuffle elements in linked list in java. It generates different order of output every time when it is invoked.

Syntax:

 Collections.shuffle(linkedList);

Example:

package com.w3schools;
 
import java.util.Collections;
import java.util.LinkedList;
 
public class Test {
  public static void main(String args[]){
	LinkedList<String> linkedList = new LinkedList<String>();
	linkedList.add("Jai");
	linkedList.add("Mahesh");
	linkedList.add("Naren");
	linkedList.add("Vivek");
	linkedList.add("Vishal");
	linkedList.add("Hemant");
	System.out.println("Actual LinkedList:"+linkedList);
	Collections.shuffle(linkedList);
        System.out.println("Results after shuffle operation:" + linkedList);      
        Collections.shuffle(linkedList);
        System.out.println("Results after shuffle operation:" + linkedList);
  }
}

Output

Actual LinkedList:[Jai, Mahesh, Naren, Vivek, Vishal, Hemant]
Results after shuffle operation:[Hemant, Mahesh, Jai, Naren, Vishal, Vivek]
Results after shuffle operation:[Hemant, Mahesh, Vishal, Naren, Vivek, Jai]
