Here's the starter code for farmer class:

package P$3$;

import java.util.Arrays;

public class Farm $\{$

private double availableFood;

private Animal$[]$ animals;

private final int MAX$\_$ANIMAL$\_$COUNT $=100$;

private int animalsCount $=0$;

$//$animalsCount is used to track the number of animals in the animals array.

$//$animalsCount should be incremented whenever we add a new animal to animals array.

public Farm$()\{$

setAvailableFood$(1000)$;

animals $=$ new Animal$[$MAX$\_$ANIMAL$\_$COUNT$]$;

add$($new Chicken$())$;

add$($new Cow$())$;

add$($new Llama$())$;

add$($new Llama$())$;

$\}$

public void makeNoise$()\{//$ all animals make their sound $($Moo$,$ Cluck, etc$)$

for$($Animal animal: getAnimals$())$

animal.sound$()$;

$\}$

public void feedAnimals$()\{//$ restore energy of all animals and deduct amount eaten from availableFood

for$($Animal animal : getAnimals$())$

if$($availableFood $>=$ Math.min$($animal$.$getMealAmount$(),(100-$animal.getEnergy$())))$

availableFood $-=$ animal.eat$()$;

else

System.out.println$("$Not enough food for your animals! You need to collect more food items."$)$;

$\}$

public void animSort$()\{$

$/*$ sorts animals according to their natural ordering criteria

$*$ Note that we cannot apply Arrays.sort to animals directly if it has null values $($i$.$e$.$ when the farm is not full$).$

$*/$

if$($animalsCount$=0$ && availableFood

this.availableFood $=$ availableFood;

$\}$

public Animal$[]$ getAnimals$()\{$

$//$returns an array with only the animals existing in the farm $-$ i$.$e$.$ doesn't return the full animals array if it has null values.

if$($animalsCount $$ MAX$\_$ANIMAL$\_$COUNT$)\{$

Animal$[]$ temp $=$ new Animal$[$animalsCount$]$;

In this part, you will implement a load$/$save feature in your game. Start by downloading the starter$\_$code

that comes with this assignment then do as required below.

$($A$)$ Farm class:

Adda methodvoid exit $($String filename$)$

$+4$ The method saves the farm data to a file named filename. Farm data includes

at least availableFood and animals $($i$.$e$.$ the array with all animal instances$)$

$[+1]$ Once saved, display a message that data was saved successfully.

$+4$ If errors $($exceptions$)$ happen during the saving process, the method should print

an error message. You should have at least two catch statements $($one of them is

FileNotFoundException$).$

$[+1]$ Make sure your code closes the output stream regardless of whether an error

happens or not.

$[+2]$ Implement any required changes in your code $($e$.$g$.$ in other classes$)$ so that this

method works.

Adda methodvoid load$($String filename$)$

$+4$ The method loads the farm data from a file named fil ename.

$+1$ Once loaded, display a message that data was load successfully.

$[+3]$ If errors $($exceptions$)$ happen during the loading process, the method should print

an error message. You should have at least three catch statements $($one of them is

FileNotFoundException$).$

$+4$ If $f$ ilename is not found: in addition to the error message from the above bullet,

initialize the game with default values, e$.$g$.$ availableFood should be $1000,$

animals array should have $100$ spots and $4$ animals: a chicken, a cow, and $2$ llamas.

$[+1]$ Make sure your code
