CODE TO COPY:

// ArrayListVsLinkedlIst class implementation
import java.util.*;

{
public static void main(String[] args)
{
// create a constant for the size of each list

// create the required objects
List<Integer> aList = new ArrayList<Integer>();
List<Integer> lList = new LinkedList<Integer>();
// declare the required variables
long start, end;
int i;
// comparison between the efficiency of the add() method
// from the ArrayList and LinkedList classes
System.out.println("Time in milliseconds to add " + SIZE
+ " numbers to each list ...");
start = System.currentTimeMillis();
for (i = 0; i < SIZE; i++)
{

}
end = System.currentTimeMillis();
System.out.println("ArrayList: " + (end - start) + " ms");

for (i = 0; i < SIZE; i++)
{
