 Example:

 public static void main(String args[])
 {
    Runnable test = 
    new Runnable()
    {
       public void run()
       {
          int i;
	  for (i = 0; i < 10; i++) {}
       }
    };

    Benchmark bmark = new Benchmark(test);
    System.out.println("This takes " + bmark.perform() + " nanoseconds.");
 }
