Im trying to create an ArrayList of LinkedLists.

I want to create an ArrayList of n elements. N is a number the user inputs. Each element of the ArrayList will have a LinkedList of size n. Once the linked lists are created I'm suppose to input data. Can someone please guide me through the process? I have provided what I have coded so far, please take a look and if something is wrong, I'd appreciate the feedback.

As far as my understanding on your question. It seems your trying to create an ArrayList that contains N number of LinkedList objects, where each LinkedList has the same size of N. If my understanding is correct, then please do the following changes to your code. First create N number of Linkedlists and add those to the ArrayList. ArrayList<LinkedList<String>> arrayList = new ArrayList<>();

for (int i = 0; i < n; i++) {
LinkedList<String> mArray = new LinkedList<>();
arrayList.add(linkedList);
}

for (int i = 0; i < n; i++) {
LinkedList<String> mArray = new LinkedList<>();
arrayList.add(linkedList);
}

Then iterate the arrayList and add values using nested for loop
