In this tutorial, we will learn java program to create an array and rotate the elements stored in the array by two positions.
That means if our array (list) is
After two rotations
Our program will first take the input of array size and then the elements of the array. Then, our program will rotate the elements of the array by 2
Case 1: if the user inputs 4 as array (list) size and the array (list) elements as 1,2,3,4.
The output should be 3, 4, 1, 2.
Case 2: if the user inputs 5 as array (list) size and the array (list) elements as 9,8,7,6,5.
The output should be 6, 5, 9, 8,7.
Java Program for Right Rotation on Array Elements by Two Position
For the input array: [1, 2, 3, 4, 5], the for loop will rotate the array 2 times.
For 1st rotation the array becomes: [5, 1, 2, 3, 4].
And finally at 2nd rotation the array becomes: [4, 5, 1, 2, 3]
