Question

Does anyone know how to do this? This is an assignment that I am working on for my Algorithm course and it has to done using NetBeans IDE 7.4. Here's how it works:

Write a program to evaluate the execution time for several types of program structures. Use the Stopwatch class described below:

public class Stopwatch:

Stopwatch () create a stopwatch
double elapsedTIme() return elapsed time since creation

typical client:

public static void main(String[] args)

{

     int N = Integer.parseInt(args[0]);

     int[] a = new int[N];

     for (int i = 0; i < N; i++)

         a[i] = StdRandom.uniform(-1000000, 1000000);

     Stopwatch timer = new Stopwatch();

     int cnt = ThreeSum.count(a);

     double time = timer.elapsedTime();

     StdOut.printIn(cnt +
