Question

Exercise 2

Write a class named Vehicle
Holds make and model (strings) and year (int)

Contains this method:

Vehicle(String make, String model, int year) {

this.make = make;

this.model = model;

this.year = year;

}

Add getters and setters for each variable

Write a class called FordMustang that extends the Vehicle class

              Create instance of object
              Pass variables
              Print

Answer 1

Please find the code for the following:

Code:

Vehicle.java:
//Write a class named Vehicle
public class Vehicle
{
   //Created 3 variables to hold model, make and year
   protected String make;
   protected String model;
   protected int year;

   //Constructor for the Vehicle class
   Vehicle(String make, String model, int year)
   {
       this.make = make;
       this.model = model;
       this.year = year;
   }
   //getters and setters for each variable
   public String getMake() {
       return make;
   }

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

   public String getModel() {
       return model;
   }

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

   public int getYear() {
       return year;
   }

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

}

FordMustang.java:
//Write a class called FordMustang that extends the Vehicle class
public class FordMustang extends Vehicle
{
   //This is for calling the constructor of the super class which is Vehicle
   FordMustang(String make, String model, int year) {
       super(make, model, year);
   }

   /*Main method*/
   public static void main(String[] args)
   {
       //Create an instance of object and pass the variables
       FordMustang veh=new FordMustang("Ford","GT 500",2001);
      
       veh.setYear(2020);
      
       //Print the variables
       System.out.println(veh.getMake());
       System.out.println(veh.getModel());
       System.out.println(veh.getYear());
   }
}
