Question

Write a class called Car.java with the following variables, constructor and methods. Variables: All variables given below must be declared as private except the color variable. color is a string value indicating the color of the car. brand is a string value indicating the brand name of the car. model is a string value indicating the model name of the car. year is an integer value indicating the production year of the car. kilometerslnK is a double value indicating how many kilometers the car has travelled. fuelType is a boolean value indicating if the car uses Gasoline (true) or Diesel (false). Write a constructor which gets color of the car as parameter and sets the related variable. First, write get and set methods for private variables. Read Information reads user inputs as in the sample output given below and assigns them to related variables. Brand: Nissan Model: Juke Year: 2013 Kilometers (in thousand): 61.3 Fuel Type (Gasoline/Diesel): Diesel priceOfCar gets an integer value (1 for sale or 2 for rent) as parameter and calculates the price of the car according to the equations, and it prints the result as in sample output given below. (You should write either 'Price for sale' or 'Price for rent according to provided parameter.) Price for sale of this car is 214750.0 TL. Sale = 100000 - (kilometersitxK * 10) - (ageOfCar * 1000) Also, add 10000 to this amount if fuel type of the car is Diesel. Rent = 200 - (kilometersinK * 0.5) - (ageOfCar * 2) Also, subtract 10 from this amount if fuel type of the car is Gasoline. printInformation prints information as given in the sample output below. (If car uses Gasoline, you should write 'using gasoline as fuel", otherwise you should write 'using diesel as fuel'.) This red car is Nissan's "Duke". It has travelled 61300.0 KM since 2013 using diesel as fuel. areCarsEqual gets one Car object as parameter and compares two cars in terms of their brand, model, year. kilometersInK and fuelType variables. Finally, it returns a boolean value indicating whether all are same or not.
