Question

Design a class named Car that has the following fields:

Answer 1

Answer:

// The class car is defined

public  class Car {

  // instance variable yearModel

  private int yearModel;

  // instance variable make

  private String make;

  // instance variable speed

  private int speed;

 

  // empty constructor

  // with instances inside it

  // the instances are from the question

  public Car(){

      yearModel = 2000;

      make = "Nissan";

      speed = 4;

  }  

  // overloaded constructor

  // constructor defined with three arguments

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

      // the arguments are assigned to the object's variable

      this.yearModel = yearModel;

      this.make = make;

      this.speed =speed;

  }

  // setter(mutator) method

  public void setYearModel(int yearModel){

      this.yearModel = yearModel;

  }

  // setter(mutator) method

  public void setMake(String make){

      this.make = make;

  }

  // setter(mutator) method

  public void setSpeed(int speed){

      this.speed = speed;

  }

  // getter(accessor) method

  public int getYearModel(){

      return yearModel;

   }

  // getter(accessor) method

  public String getMake(){

      return make;

   }

  // getter(accessor) method

  public int getSpeed(){

      return speed;

   }  

  // toString is override to display the car object properties

  public String toString(){

      return "Car's year model: " + getYearModel() + ", make: " + getMake() + ", speed: " + getSpeed();

  }

}

Explanation:

The code is well commented.
