Using your preferred IDE or this online IDE, perform the following steps. Create a public class named Party. (If you are using the recommended online IDE, remove 'public'.)
Declare a private int variable named numGuests.
Declare two (2) methods named getNumGuests (of int type) and setNumGuests. The getNumGuests method shall return the value of numGuests. Below is the code for setNumGuests.
public void setGuests(int numGuests) {
this. numGuests = numGuests;
}
Declare another method named displayMessage with a println statement saying "Enjoy the party!"
Create another class named BirthdayParty. This class should be a subclass of the Party class.
In the main method, create a BirthdayParty object named bday.
Declare an int variable to accept the number of guests attending the birthday party.
Use the setNumGuests method on bday to store the value of that variable .
Display the number of guests by calling getNumGuests then call displayMessage.
Sample output:

Enter number of guests: 40

40 guests have been invited.

Enjoy the party!
