Create a project: FinalEXam Create a package: finalexam Write an automobile class, Automobile, that contains an odometer (integer) and a tripmeter (integer) as a minimum. You may need other variables as well. Include a default constructor that inititalizes all instance variables. Include getters and setters for each instance variable. Overload the constructor to accept a tripmeter value. Include an initializeTrip method that resets the trip meter. Include a startTrip method that gets the odometer reading and starts the tripmeter. Include a stopTrip method that sends how many miles were traveled on a trip. You must be able to start and stop the trip during the session. Save the odometer value in a file so when the next trip is started you begin with the last saved value. Read the odometer value each time the program starts. The file name must be odometerReading.txt and contain 1100 (for 1100 miles).initially. The second file name must be tripmeter.txt and contain 0 (for 0 miles) initially Overload the toString method to return the original odometer reading, the trip meter reading and the final odometer reading. Write a driver application class (Main) that uses and verifies that all methods of the Automobile class work correctly. Use the following code for the Main class: /** * Write a description of class Main here. * * @author (your name) * @version (a version number or a date) */ public class Main { public static void main(String[] args) { Automobile auto = new Automobile(); auto.initializeTrip(); auto.startTrip(); auto.stopTrip(150); auto.startTrip(); auto.stopTrip(140); auto.startTrip(); auto.stopTrip(130); auto.startTrip(); auto.stopTrip(125); System.out.println(auto); } }
