Write a java program for a Toy Car Application. This Car Control can be used to command a electric toy car to power on, power off, go fast, slow down, turn left and turn right.

 

Create an interface "Controllable" which specifies the following abstract methods:

 

    void powerOn();

 

    void powerOff();

 

    void turnRight();

   

    void turnLeft();

   

    void goFaster();

  

void slowDown();

 

Define an ElectricCar class that implements the following methods:

 

void powerOn ()

This method sets a flag to indicate the car is powered on

 

void powerOff ()

This method sets a flag to indicate the car is powered off.

 

void turnRight()

Turns the car by 5 degrees to the right.

 

void turnLeft()

Turns the car by 5 degrees to the left

 

void goFaster ()

Commands the car to move forward and increase the car speed by 2 mph.  

 

void slowDown ()

Commands the car to reduce the speed by 2 mph.

 

String toString()

Override this method to output the car information.

 

 

Use the following main method to test your program:

 

public class ElectricCarApp {

 public static void main(String[] args) {

    

  Controllable toy = new ElectricCar();

    

    toy.powerOn();

    toy.goFaster();

    toy.turnLeft();

    System.out.println(toy);

    toy.turnLeft();

    System.out.println(toy);

    toy.slowDown();

    System.out.println(toy);   

    toy.powerOff();

    toy.turnRight();

    System.out.println(toy);    

 }

}

 

 

Expected Output:

car travels in 355 deg at the speed of 2 mph

car travels in 350 deg at the speed of 2 mph

car is stopped

car is powered off
