Programming Assignment #8-Automobile In this assignment, we will have 3 java class files. CarModeljava, Automobile java, AutomobileDemojava Step 1: Design an enum (chp 6.12) called CarModel in a CarModel java file). Think of at least three values for the constants e.g., CAMRY, CIVIC FOCUS etc. Step 2: Next, design a class called Automobile (in a Automobile java file), which has the following class attributes A class private attribute for the year what data type are you going to use?) A class private attribute for the model (of type CarModel the enum created in Step 1) Ano argument constructor that initializes year to 0 and model to null. An overloaded constructor which takes 2 inputs (int year and CarModel model) and will initialize the instance fields A copy constructor for Automobile A copy0 method to create a copy of the Automobile object. An equals0 method to compare 2 different Automobile objects. Atostring method which will display the automobile's year and model. Because Model is an enumerated type, use a switch statement to initialize the model String to print. The output formatting is completely up to you. For example: "Year: 2016 Model: Maxima" getters (Accessors) and setters (Mutators) for year and model.

Explanation / Answer

public enum CarModel{CAMRY,CIVIC,FOCUS};
public class Automobile
{
    private int year;
    private CarModel cm;
  
    public Automobile()
    {
        year = 0;
        this.cm =null;
    }
  
    public Automobile(int year,CarModel cm)
    {
        this.year = year;
        this.cm = cm;
    }
    public Automobile(Automobile am)
    {
        this.year = am.year;
        this.cm = am.cm;
    }
    public Automobile copy(Automobile AM)
    {
      
        this.year = AM.year;
        this.cm = AM.cm;
        return this;
    }
  
    public boolean equals(Automobile am)
    {
        if (year == am.year && cm == am.cm)
        return true;
        else
        return false;
    }
    public String toString()
    {
        String cmValue;
        switch(cm)
        {
            case CAMRY: cmValue = "CAMRY";
                    break;
            case CIVIC: cmValue = "CIVIC";
                    break;
            case FOCUS: cmValue = "FOCUS";
                    break;
            default : cmValue = " ";
                    break;
        }
        return "Year :"+year + " Model : "+cmValue;
    }
    public void setYear(int year)
    {
        this.year = year;
    }
    public void setCM(CarModel cm)
    {
        this.cm = cm;
    }
    public int getYear()
    {
        return year;
    }
    public CarModel getCM()
    {
        return cm;
    }
  
  
  
  
  
}
  

public class AutomobileDemo
{
   public static void main (String[] args)
   {
        CarModel cm = CarModel.CAMRY;
      
        Automobile car1 = new Automobile(2000,cm);
        Automobile car2= new Automobile(car1);
      
        Automobile car3 = new Automobile();
      
        car3.copy(car2);
      
        car3.setYear(2015);
      
        if(car1.equals(car2))
        System.out.println(" Car1 is equal to Car2");
        else
        System.out.println(" Car1 is not equal to Car2");
      
      
        if(car2.equals(car3))
        System.out.println(" Car2 is equal to Car3");
        else
        System.out.println(" Car2 is not equal to Car3");
      
      
      
        if(car1.equals(car3))
        System.out.println(" Car1 is equal to Car3");
        else
        System.out.println(" Car1 is not equal to Car3");
      
      
        System.out.println("Car1 = "+car1);
        System.out.println("Car2 = "+car2);
        System.out.println("Car3 = "+car3);
      
      
      
  
   }
}

Output:

Car1 is equal to Car2

Car2 is equal to Car3

Car1 is equal to Car3

Car1= Year : 2000 Model : CAMRY

Car2= Year : 2000 Model : CAMRY

Car3= Year : 2015 Model : CAMRY
