Create a class called Car that includes three instance variables—a model (type
String), a year (type String), and a price (double). Provide a constructor that initializes the three
instance variables. Provide a set and a get method for each instance variable. If the price is not positive,
do not set its value. Write a test application named CarApplication that demonstrates class Car’s capabilities. Create two Car objects and display each object’s price. Then apply a 5% discount on the
price of the first car and a 7% discount on the price of the second. Display each Car’s price again.

Answer:

class Car {

 private String model;

 private String year;

 private double price;

 public Car(String model, String year, double price) {

   this.model = model;

   this.year = year;

   if (price > 0) {

     this.price = price;

   }

 }

 public String getModel() {

   return model;

 }

 public void setModel(String model) {

   this.model = model;

 }

 public String getYear() {

   return year;

 }

 public void setYear(String year) {

   this.year = year;

 }

 public double getPrice() {

   return price;

 }

 public void setPrice(double price) {

   if (price > 0) {

     this.price = price;

   }

 }

}

class CarApplication {

 public static void main(String[] args) {

   Car car1 = new Car("Toyota", "2020", 20000);

   Car car2 = new Car("Honda", "2019", 25000);

   System.out.println("Original price of car1: $" + car1.getPrice());

   System.out.println("Original price of car2: $" + car2.getPrice());

   car1.setPrice(car1.getPrice() * 0.95);

   car2.setPrice(car2.getPrice() * 0.93);

   System.out.println("Discounted price of car1: $" + car1.getPrice());

   System.out.println("Discounted price of car2: $" + car2.getPrice());

 }

}
