In NetBeans, create a Java program for the following:

1. Design a class named StopWatch. The class contains:

Private data fields startTime and endTime with accessor (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.

2. Write a test program that measures the execution time of sorting 100,000 integer numbers using:

bubble sort

selection sort

insertion sort
