Help with java problem

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
