Explanation / Answer

Hi

I have modified the code and highlighted the code changes below.

public static ArrayList<Integer> doArrayListSearchGreatest(int numItems) {
System.out.print("doArrayListSearchGreatest: ");
ArrayList<Integer> list = new ArrayList<Integer>();

// TODO Write code that adds integers 0 through (numitems - 1)
// to list.
for(int i =0; i<=numItems-1; i++){
   list.add(i);
}

long startTime = getTimestamp();

// TODO Write code that gets the element at the last index from list.
int lastNumber = list.get(list.size()-1);

long endTime = getTimestamp();
long totalTime = endTime - startTime;
System.out.println(totalTime);
  
return list;
}
