JAVA PROGRAMMING

Design and implement a class named StopWatch. The class contains:

• Data fields startTime and endTime.
• Methods getStartTime and getEndTime that return startTime and endTime, respectively.
• 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 printing 1,000,000 numbers using for loop.

Hint: For this question, you need to use instances of Date class to implement your StopWatch class. Therefore, you need to look at the Java 8 API and search for Date class and browse its constructors and methods.
