This is Restaurant class which extending the store class defined in the question. As the ques states, without implementing the store class... I just extend it to fetch the name of restaurant.
class Restaurant extends store{
int total_people_served, max_occupancy,
current_occupancy;
double price_per_person;
public Restaurant(int total_people_served, int
max_occupancy, int current_occupancy, double
price_per_person){
this.total_people_served=
total_people_served;
this.max_occupancy=
max_occupancy;
this.current_occupancy=
current_occupancy;
this.price_per_person=
price_per_person;
}
public int seat_patrons(int numOfPeopleSeated){
int check=
this.current_occupancy+numOfPeopleSeated;
if(check <=
this.max_occupancy){
serve_patrons(numOfPeopleSeated);
this.total_people_served+=numOfPeopleSeated;
this.current_occupancy+=numOfPeopleSeated;
return 1 ;
}
else
return 0;
}
public void serve_patrons(int num){
System.out.println("number of
people being served: "+ num);
}
public void checkOut(int
checkout_total){
this.current_occupancy-=checkout_total;
System.out.println("current
occupancy: "+ this.current_occupancy);
}
public static void main(String[] args){
int ch, ch_in;
Scanner sc= new
Scanner(System.in);
store s1= new store();
s1.setName("KFC");
Restaurant r1= new Restaurant(100,
15, 10, 500);
System.out.println("Enter number of
people arrive: ");
ch_in= sc.nextInt();
int res=
r1.seat_patrons(ch_in);
if(res == 1){
System.out.println("Welcome to "+ s1.getName());
}else
System.out.println("We are at capacity, we appreciate your
patience");
System.out.println("Enter number of
people for checkout: ");
ch= sc.nextInt();
r1.checkOut(ch);
}
}
The Store class:
public store(){
}
public store(String name,String address, int status, double
sales_tax_percentage){
this.name= name;
this.address=address;
this.status=status;
this.sales_tax_percentage= sales_tax_percentage;
}
public String getName(){
return this.name;
}
public void setName(String name){
this.name= name;
}
public String getAddress(){
return this.address;
}
public void setAddress(String address){
this.address= address;
}
public int getStatus(){
return this.status;
}
public void setStatus(int status){
this.status= status;
}
public double getsales_tax_percentage(){
return this.sales_tax_percentage;
}
public void settsales_tax_percentage(double
sales_tax_percentage){
this.sales_tax_percentage= sales_tax_percentage;
}
}
Now run the program and outputs are follows:
in here max capacity= 15, So when I gave input 4 as number of people arrived
current occupancy was 10, 10+4 = 14,
14< 15, that's why it prints welcome message.
Then check out people input is given as 3, so,
current occupancy= 14,, 14- 3= 11,
and it shows current occupancy as 11 in output.
On 2nd time running of code:
I gave input as 7,
So, current occupancy= 10, i.e. 10+7= 17,
Max occupancy = 15, Which is smaller then current arrival of people
Thus shows "the patience" message.

Here is a sample run of the tester program: Make sure your program follows the Java Coding Guidelines. Consider the following class: /** * A store superclass with a Name and Sales Tax Rate */ public class Store { public final double SALES_TAX_RATE = 0.06; private String name; /** * Constructor to create a new store * @param newName */ public Store(String newName) { name = newName; } ...
In Java, Write a class encapsulating a restaurant,which inherits from Store. A restaurant has the following additional attributes: how many people are served every year and the average price per person. code the constructor, accessors, mutators, toString and equals method of the new subclass; also code a method returning the average taxes per year. You also need to include a client class to test your code for both the parent class and the subclass. Code for Store below(Super class aka...

Implement an abstract class named Person and two subclasses named Student and Staff in Java. A person has a name, address, phone number and e-mail address. A student has a credit hour status (freshman, sophomore, junior, or senior). Define the possible status values using an enum. Staff has an office, salaray, and date-hired.
