Question

Write a class named Car that has the following member variables: - yearModel. An int that holds the car’s year model. - make. A string that holds the make of the car. - speed. An int that holds the car’s current speed. The class should have the following member functions: - Appropriate accessor functions to get the values stored in an object’s yearModel, make, and speed member variables. - accelerate function that adds 5 to the speed member variable each time it is called. - brake function that subtracts 5 from the speed member variable each time it is called.

Answer 1

Answer:

public class Car {

//Member variables    

private int yearModel;

   private String make;

   private int speed;

   //Constructor

   public Car(int yearModel, String make, int speed) {

       this.yearModel = yearModel;

       this.make = make;

       this.speed = speed;

   }

   //Accessor Methods getters and setters

   public int getYearModel() {

       return yearModel;

   }

   public void setYearModel(int yearModel) {

       this.yearModel = yearModel;

   }

   public String getMake() {

       return make;

   }

   public void setMake(String make) {

       this.make = make;

   }

   public int getSpeed() {

       return speed;

   }

   public void setSpeed(int speed) {

       this.speed = speed;

   }

   //Accelerate function

   public void accelerate(){

       this.speed+=5;

   }

   // Brake function

   public void brake(){

       this.speed-=5;

   }

}

Explanation:

• As required by the question, The class Car is created using Java programming language
• The members variables, the constructor, The accessor methods are all created as required by the question (Please pay attention to the comments added to the code)
• The accelerate and brake functions that add and subtract 5 from the speed member variable respectively are also created.
