Here is snakeworld

Question

Can someone please provide me the code for the snake project of a+ computer science? 
Here is SnakeWorld:
import java.awt.Color;
import java.util.ArrayList;
import info.gridworld.grid.Grid;
import info.gridworld.actor.Actor;
import info.gridworld.grid.Location;
import info.gridworld.actor.ActorWorld;
import info.gridworld.grid.BoundedGrid;

public class SnakeWorld extends ActorWorld
{
private int foodDelay;
private Snake snake;
private boolean gameOn=true;

public SnakeWorld(int width, int height)
{
super(new BoundedGrid(width, height));
Grid grid = getGrid();
snake = new Snake();
snake.putSelfInGrid(grid, new Location(4,7));
foodDelay = (int)(Math.random()*grid.getNumRows() * 3);
setMessage("The Snake Game - Eat as many monkees as you can!");
}

public void step()
{
if(snake.isDead())
{
setMessage("Your snake is dead! He ate "+ snake.getFoodEaten() + " monkees!");
}
else
{
//make sure the Grid is not null

setMessage("The Snake Game!!! - " + snake.getFoodEaten() + " monkees eaten so far!");

//make the Snake move


//if there is no Food
//add some Food
}
}

public boolean isFoodAllGone()
{
//check the grid to see if any Food remains
//instanceof might prove useful

return true;
}

public void addFood()
{
//write the code to randomly place 1 Food in the grid
}

public boolean keyPressed(String description, Location loc)
{
//write the code to change the direction of the Snake 
if(!gameOn)
{
return true;
}
ArrayListlocs = getGrid().getOccupiedLocations();
for(int i = locs.size()-1; i>=0; i--)
{
if(!getGrid().get(locs.get(i))instanceof Snake)
{
locs.remove(i);
}
}

Snake snake = (Snake)(getGrid().get(locs.get(0)));
if(description.equals("LEFT"))
{
snake.setDirection(Location.WEST);
}
if(description.equals("RIGHT"))
{
snake.setDirection(Location.EAST);
}
if(description.equals("UP"))
{
snake.setDirection(Location.NORTH);
}
if(description.equals("DOWN"))
{
snake.setDirection(Location.SOUTH);
}
return true;

}
}

Here is Section:
import java.awt.Color;
import info.gridworld.actor.Actor;

public class Section extends Actor
{
public Color getColor(){
return null;
}
}


Here is Food:
import java.awt.Color;
import info.gridworld.actor.Actor;

public class Food extends Actor
{
public Color getColor(){
return null;
}
