Description
Design a class named Clock. The class contains private data fields for startTime and stopTime, a no argument constructor that initializes the startTime to the current time, a method named start() that resets the startTime to the given time, a stop() method that sets the endTime to the given time and a getElapsedTime() method that returns the elapsed time in seconds. Create a TestClock class to construct a Clock instance and return the elapsed time. Command line arguments should be used to send the start and end times. You should use the java.time classes. Here is sample run:
