Question

public static ArrayList<Integer> doArrayListSearchMedian(int numItems) {

       System.out.print("doArrayListSearchMedian: ");

       ArrayList<Integer> list = new ArrayList<>();

       // TODO Write code that adds integers 0 through (numitems - 1)

       // to list.

       long startTime = getTimestamp();

       // TODO Write code that gets the element at the median value.

       long endTime = getTimestamp();

       long totalTime = endTime - startTime;

       System.out.println(totalTime);

       return list;

   }

Explanation / Answer

Hi,

I have implemented the code in required areas. Highlighted the code changes below.

   public static ArrayList<Integer> doArrayListSearchMedian(int numItems) {
   System.out.print("doArrayListSearchMedian: ");
   ArrayList<Integer> list = new ArrayList<Integer>();
   // TODO Write code that adds integers 0 through (numitems - 1)
   // to list.
   for(int i=0; i<numItems; i++){
       list.add(i);
   }
   long startTime = getTimestamp();
   // TODO Write code that gets the element at the median value.
   int index = list.size()/2;
   int medianElement = list.get(index);
   long endTime = getTimestamp();
   long totalTime = endTime - startTime;
   System.out.println(totalTime);
  
   return list;
   }
