Java program to right rotate an Array by 1 element

[Kris-nfld]

Thank you for this video! In 13 mins you managed to help me understand shifting elems in array better than in 1 hour of my "Java course" :) Thanks for your work!

Thank you so much, i totally understand your explanation! I was trying to do something similar but i thought i could do it with incrementing i. Could you help me understand what I am missing in the following code?
public static void rotateGroceries(String[] groceryList) {
if(groceryList.length>1){
String lastElement =
for(int i = 0; i< groceryList.length-1; i++){
if(i==0){
groceryList[i] = lastElement;
}else{
groceryList[i] = groceryList[i+1];
}


}
In my output, the last element seems to take over most of the positions but I don t really understand why
