A method named start that resets the start Time to the current time. A method named stop that sets the end Time to the current time. A method named get Elapsed Timel that returns the elapsed time for the stopwatch in milliseconds. Write a test program that measures the execution time of sorting 100,000 numbers (generated randomly in the range of 0 to 100) using the following selection sort method: + = /** The method for sorting the numbers */ public static void selection Sort(int[] list) { for (int i = 0; i list[i]) { Current Mio list[i]; currentMinIndex = j; } // Swap list[i] with list[current MiaIndex] if necessary; if (current Miot dezut i) { list[current Mia Index] list[i]; list[i] = current Mia = }
