Why do I not need to create a Carly object for the Carly class in the CarlyEventDemo class when I need to make an object for the CarlyEvent class? Code below and any explanation would be greatly appreciated.

import java.util.Scanner;

public class Carly $\{$

public static void main$($String $[]$ args$)\{$

$//$variable

int guests;

$//$CarlyEvent event $=$ new CarlyEvent$()$;

motto$()$;

guests $=$ numGuests$()$;

price$($guests$)$;

$\}$

public static int numGuests$()\{$

$//$variable

int numOfGuests;

$//$Scanner

Scanner input $=$ new Scanner$($System$.$in$)$;

System.out.println$("$How many people will be attending the event? $")$;

numOfGuests $=$ input.nextInt$()$;

return numOfGuests;

$\}$

public static void motto$()\{$

$//$motto

System.out.println$("**************************************************")$;

System.out.println$("**")$;

System.out.println$("*$ Carly's makes the food that makes it a party. $*")$;

System.out.println$("**")$;

System.out.println$("**************************************************")$;

$\}$

public static void price$($int guests$)\{$

int ticketCost $=35$;

int total;

total $=$ guests $*$ ticketCost;

System.out.println$("$You have $"+$ guests $+"$ guests attending the event, thus the total price is $$"+$ total$)$;

boolean largeEvent $=($guests $>=50)$;

System.out.println$("$Large event: $"+$ largeEvent$)$;

$\}$

public static String getEventNum$()\{$

$//$variable

String eventNumber;

Scanner input $=$ new Scanner$($System$.$in$)$;

System.out.println$("$What is the event number? $")$;

eventNumber $=$ input.next$()$;

return eventNumber;

$\}$

$\}$

public class CarlyEvent $\{$

public final static int pricePerGuest $=35$;

public final static int largeGroup $=50$;

private String eventNum;

private int numGuest;

private int price;

$//$event number

public String getEventNumber$()\{//$get

return eventNum;

$\}$

public void setEventNumber$($String eventNum$)\{//$set

this.eventNum $=$ eventNum;

$\}$

$//$guests

public int getGuest$()\{//$get

return numGuest;

$\}$

public void setGuest$($int numGuest$)\{//$set

this.numGuest $=$ numGuest;

price $=$ numGuest $*$ pricePerGuest;

$\}$

public int getPrice$()\{//$get

return price;

$\}$

$\}$

public class CarlyEventDemo $\{$

public static void main$($String $[]$ args$)\{$

$//$variables

$//$int price;

int numOfGuests;

String eventNum;

$//$objects

CarlyEvent event $=$ new CarlyEvent$()$;

Carly.motto$()$;

eventNum $=$ Carly.getEventNum$()$;

numOfGuests $=$ Carly.numGuests$()$;

Carly.price$($numOfGuests$)$;

event.setEventNumber$($eventNum$)$;

event.setGuest$($numOfGuests$)$;

System.out.println$("$Event number: $"+$ event.getEventNumber$()+"$

Number of guests: $"+$ event.getGuest$())$;

$\}$

$\}$
