Question

Program9.java

Two files are required, a data class named Car and an executable class named CarsTest.

Class Car (data class, no main method)

  • five instance data members, all private: String make, String model, int year, double price, String color.
  • For price make sure the output is in two decimal format with $ in the front
  • one static, or class, member named unitsSold assigned a value of zero. Make it public.
  • no-arg constructor, and another parameterized constructor that sets values in all data members when called. Both constructors should increment the unitsSold static data member.
  • has setters and getters for each data member.
  • toString() method that returns the state of all data members of a Car instance

In Class CarsTest 

  • code a main method and another value-returning method named carsValue
  • In main: 
    • create at least six Car instances, ensuring that at least three have model years less than 2018.
    • create at least four Car instances using the parameterized constructor.
    • create at least two more Car instances with the no-arg constructor
    • use the Car class setter methods to assign values to all data members of these two cars.
    • use the "array initializer" syntax to make an array to hold all Car objects.
    • call the method named carsValue with the array as its sole argument.
    • print the value returned by carsValue and the value in the unitsSold data member. 
  • In carsValue
    • use a foreach loop to process the array passed into the method as follows:
    • reduce the price of all vehicles with model years less than 2018 by 25%.
    • print the state of each Car object using the toString method.
    • calculate the total value of the Car objects in the array.
    • return the total value to main.
