Question

In the previous lab you created a Car class and a Dealership class. Now, in this activity change the
design of the Dealership class, in which the list of the cars inside a dealership will be stored in an ArrayList.
Then, provide required getter and setter methods to keep the records of all its cars. In your tester class, test
your class and also printout the list of all cars of a given dealership object.

// Java program

import java.util.ArrayList;

class Car {
String make;
String model;
int year;
double transmission;
int seats;
int maxSpeed;
int wheels;
String type;

public Car() {

}

public Car(String make, String model, int year, double transmission, int seats, int maxSpeed, int wheels, String type) {
this.make = make;
this.model = model;
this.year = year;
this.transmission = transmission;
this.seats = seats;
this.maxSpeed = maxSpeed;
this.wheels = wheels;
this.type = type;
}

public void setMake(String make) {
this.make = make;
}

public void setModel(String model) {
this.model = model;
}

public void setYear(int year) {
this.year = year;

public void setTransmission(double transmission) {
this.transmission = transmission;
}

public void setSeats(int seats) {
this.seats = seats;
}

public void setMaxSpeed(int maxSpeed) {
this.maxSpeed = maxSpeed;
}

public void setWheels(int wheels) {
this.wheels = wheels;

public class TestDealer {
public static void main(String[] args) {

Car car2 = new Car();
car2.setMake("Nissan");
car2.setModel("Altima");
car2.setMaxSpeed(275);
car2.setSeats(5);
car2.setYear(2018);
car2.setTransmission(16.25);
car2.setType("Sedan");
car2.setWheels(4);

Dealership d1 = new Dealership("Auto Dealer", "Woodland");
ArrayList<String> e = new ArrayList<>();
e.add("John");
e.add("Sam");

ArrayList<String> m = new ArrayList<>();
m.add("Adam");
m.add("Bob");

d1.setEmployees(e);
d1.setManagers(m);
d1.addCar(car1);
d1.addCar(car2);

System.out.println("Dealership Information:");
System.out.println("Name: "+d1.getName());
System.out.println("Location: "+d1.getLocation());
System.out.println("Employees: "+d1.getEmployees());
System.out.println("Managers: "+d1.getManagers());
System.out.println("Cars: "+d1.getCars());
}
}

some modification has been done on the return type of arraylist in get and set method go throuh it and check the details .
