Explore the Java Collections Rotate Method

See how to use the rotate method in Collections to rotate the elements to a specified position.

import java.util.*;public class UsingRotateInCollections {      public static void main(String args[])   {      UsingRotateInCollections usingRotateInCollections = new UsingRotateInCollections();      usingRotateInCollections.proceed();   }      private void proceed()   {      //Creating  a list with default values      List defaultList = new ArrayList();      defaultList.add(1);      defaultList.add(2);      defaultList.add(3);      defaultList.add(4);      defaultList.add(5);      defaultList.add(6);      defaultList.add(7);      defaultList.add(8);      System.out.println("List as added: " + Arrays.toString(defaultList.toArray()));      Collections.rotate(defaultList, 2); //Rotating the list elements by 2 positions      System.out.println("List after rotate with 2 positions: "+Arrays.toString(defaultList.toArray()));   }}/*

Expected output:

[root@mypc]# java UsingRotateInCollectionsList as added: [1, 2, 3, 4, 5, 6, 7, 8]List after rotate with 2 positions: [7, 8, 1, 2, 3, 4, 5, 6]*/
