Java Program to right rotate the elements of an array
class RotateRight {
public static void main(String[] args) {
//Initialize array
int [] arr = new int [] {1, 2, 3, 4, 5};
//n determine the number of times an array should be rotated.
int n = 3;
//Displays original array
System.out.println("Original array: ");
for (int i = 0; i < arr.length; i++) {
System.out.print(arr[i] + " ");
}
//Rotate the given array by n times toward right
for(int i = 0; i < n; i++){
int j, last;
//Stores the last element of array
last = arr[arr.length-1];
for(j = arr.length-1; j > 0; j--){
//Shift element of array by one
arr[j] = arr[j-1];
}
//Last element of array will be added to the start of array.
arr[0] = last;
}
System.out.println();
//Displays resulting array after rotation
System.out.println("Array after right rotation: ");
for(int i = 0; i< arr.length; i++){
System.out.print(arr[i] + " ");
}
}
}
Output:
Original Array:
1 2 3 4 5
Array after right rotation:
3 4 5 1 2
