in JAVA: Design a class named StopWatch. The class contains:

Private data fields startTime and endTime with getter methods.

A no-arg constructor that initializes startTime with the current time.

A method named start() that resets the startTime to the current time.

A method named stop() that sets the endTime to the current time.

A method named getElapsedTime() 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 selectionSort(int[] list) {

for (int i = 0; i

// Find the minimum in the list[i..list.length-1]

int currentMin = list[i];

int currentMinIndex = i;

for (int j = i + 1; j

if (currentMin > list[j]) {

currentMin = list[j];

currentMinIndex = j;

}

}

// Swap list[i] with list[currentMinIndex] if necessary;

if (currentMinIndex != i) {

list[currentMinIndex] = list[i];

list[i] = currentMin;

}

}

}

Objectives: In this lab, the following topic will be covered: 1. Objects and Classes . Task Design a class named StopWatch. The class contains: Private data fields startTime and end time with getter methods. A no-arg constructor that initializes startTime with the current time. 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 getElapsed Timed 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 selectionsort(int[list) { for (int i = 0; i list[5) { Surco Mia = list[5]; Surco Mintadex - j; > 3 // swap list[i] with distil.curcat Mintadex) if necessary; if (currentMioIndex != 1) { listisurcentMinIndex] list[i]; distil surcent Mind
