Java program to cyclically rotate an array by one.
To rotate the contents of an array cyclically −
- create an empty variable. (temp)
- save the last element of the array in it.
- Now, starting from the nth element of the array, replace the current element with the previous element.
- Store the element in temp in the 1st position.
Example
import java.util.Arrays;
import java.util.Scanner;
public class CyclicallyRotateanArray {
public static void main(String args[]){
Scanner sc = new Scanner(System.in);
System.out.println("Enter the required size of the array ::");
int size = sc.nextInt();
int [] myArray = new int[size];
System.out.println("Enter elements of the array");
for(int i=0; i< size; i++){
myArray[i] = sc.nextInt();
}
System.out.println("Contents of the array: "+Arrays.toString(myArray));
int temp = myArray[size-1];
for(int i = size-1; i>0; i--){
myArray[i] = myArray[i-1];
}
myArray[0] = temp;
System.out.println("Contents of the cycled array: "+Arrays.toString(myArray));
}
}Output
Enter the required size of the array :: 5 Enter elements of the array 14 15 16 17 18 Contents of the array: [14, 15, 16, 17, 18] Contents of the cycled array: [18, 14, 15, 16, 17]
