Rewrite using iteration 

public Item get(int index) { if (index < 0 || index >= size) { throw new IndexOutOfBoundsException(); } int i = 0; Node current = sentinel.next; while (i != index) { current current.next; i++; = } return current.item; }
Transcribed Image Text:public Item get(int index) { if (index < 0 || index >= size) { throw new IndexOutOfBoundsException(); } int i = 0; Node current = sentinel.next; while (i != index) { current current.next; i++; = } return current.item; }
Expert Solution
Step 1

Here is a rewritten version of the get method using iteration:

public Item get(int index) {
    if (index < 0 || index >= size) {
        throw new IndexOutOfBoundsException();
    }

    Node current = sentinel.next;
    for (int i = 0; i < index; i++) {
        current = current.next;
    }
    
    return current.item;
}
