Vehicles (25 points) Name: Vehicle.java and Car.java Implement a Vehicle class that meets the following specification represented as a UML class diagram. The attributes are indicated as being private in the UML diagram, but it's also acceptable to make them protected. Implement a Car class that is a subclass of Vehicle that meets the following specification represented as a UML class diagram and overrides toString(). Numeric attributes are to have default values of 0. String attributes are to have default values of "abc". The toString() for each class should contain the name of the class, the name, and if a Car the plate, in parentheses, the at symbol, and then the speed followed by mph. For example: "Vehicle (abc) @ 0.0 mph" "Car (Jaguar, ABC-123) @ 120.5 mph" Do not modify the contents of the provided TestVehicles.java. Also note that the attribute and method names will need to match the specification exactly. TestVehicles.java: public class TestVehicles { public static void main(String[] args) { Vehicle v1 = new Vehicle(); System.out.println("toString(): " + v1); Vehicle v2 = new Vehicle(5000.5, "Shuttle"); System.out.println("toString(): " + v2); v1.setSpeed(123.456); v1.setName("Some vehicle"); v2.setSpeed(0.0); v2.setName("Nameless"); Car c1 = new Car(); System.out.println("toString(): " + c1); Car c2 = new Car(120.5, "Jaguar", "ABC-123"); System.out.println("toString(): " + c2); Vehicle v3 = new Car(145.5, "Porsche", "XYZ-456"); System.out.println("toString(): " + v3); System.out.println(); c1.setSpeed(789.123); c1.setName("Junk"); c1.setPlate("XYZ-123"); c2.setSpeed(0.0); c2.setName("Honda"); c1.setPlate("111-222"); printVehicle(v1); printVehicle(v2); printVehicle(c1); printVehicle(c2); printVehicle(v3); } public static void printVehicle(Vehicle v) { System.out.println("Print Vehicle"); System.out.println("tSpeed: " + v.getSpeed()); System.out.println("tName: " + v.getName()); System.out.println(); } } Sample Run (TestVehicles.java): toString(): Vehicle (abc) @ 0.0 mph toString(): Vehicle (Shuttle) @ 5000.5 mph toString(): Car (abc, abc) @ 0.0 mph toString(): Car (Jaguar, ABC-123) @ 120.5 mph toString(): Car (Porsche, XYZ-456) @ 145.5 mph Print Vehicle Speed: 123.456 Name: Some vehicle Print Vehicle Speed: 0.0 Name: Nameless Print Vehicle Speed: 789.123 Name: Junk Print Vehicle Speed: 0.0 Name: Honda Print Vehicle Speed: 145.5 Name: Porsche 2. Payroll (25 points) Name: Payroll.java Write a program that reads a text file named payroll.txt such that each line contains a first name, a last name, and a salary. Assume each is separated by a single space. Print each line out to the screen. Calculate the average of the salaries and display it on the screen as well. Do not ask the user for the name of the file, assume the file is named payroll.txt. Be aware that the actual text file used for grading may be different than the sample file provided, so do not assume the number of lines in the file, etc. Sample Run: File Contents: John Doe 23400.0 Jane Doe 23400.0 John Smith 12340.0 Vader Smith 99000.99 Jack Sparrow 2.19 Bob Builder 80000.0 Pizza Lord 120000.0 Average: $51163.311428571425 Where payroll.txt looks like: John Doe 23400.0 Jane Doe 23400.0 John Smith 12340.0 Vader Smith 99000.99 Jack Sparrow 2.19 Bob Builder 80000.0 Pizza Lord 120000.0
