Question

6) Complete the following Car class according to requirements.

Public class Car {

int year;

String model;

double speed;

} // end of Car

//define a constructor which accepts a car’s year and model as arguments and use them to initialize the values for the year and maker attributes. (2 points)

//define a public method, getSpeed, that returns a double value for the instance variable, speed

// and this method does not have an argument. (1 point)

//define public method, setSpeed; that has double type argument (1 point)

//define a public method, goBreak, which does not have any argument and not return anything.

// When this method is called, if the instance variable, speed, is greater than 10, it reduces the speed

// by 10; otherwise, it sets the speed to zero. (2 Pts)

Explanation / Answer

Car.java

public class Car {
   private int year;
   private String model;
   private double speed;
   public Car1(int year, String model) {
       super();
       this.year = year;
       this.model = model;
   }
   public double getSpeed()
   {
       return speed;
   }
   public void setSpeed(double speed)
   {
       this.speed=speed;
   }
   public void goBreak()
   {
       if(speed>10)
           speed-=10;
       else
           setSpeed(0);
   }
   @Override
   public String toString() {
       return "Car [Year=" + year + ",Model=" + model + ", Speed=" + speed+ "]";
   }

}
