Question

Objectives This is one of three major programming projects this semester. You should NOT collaborate on this project. While you may ask for assistance in debugging, this project should be ENTIRELY your own work. Objectives include: . Use local variables. • Use arithmetic expressions. • Use Scanner to input values. • Use a class constant. • Use of nested branches. • Use for loxops. • Use of methods. • Use of arrays. Hand-in Requirements All projects and laboratories will be submitted electronically through Blackboard. Zip up your entire project directory to submit as the source. (Right click on the project folder and follow 7-Zip > Add to "project2.zip".) The project folder should include the following two files: • Restaurant Front Desk.java • Restaurant Front Deskoutput.txt Tasks Create a directory called project2. Write a program called RestaurantFront Desk and save it in project. The program will print Spring 2020 - $1093 - Section pox - Project 2 - written by YOURNAME Note that YOURNAME and (XIX should be replaced. The program will also perform the following process: Perform the activities of a front desk in a restaurant. The program should work prompting a menu to the user that will have four basic options: 0 - Exit. 1 - New customer, 2 - Empty table, and 3 - Print occupied tables. In the following image is an example of what your output should look like (user input is in purple color):

Answer 1

import java.util.*;

class RestaurantFrontDesk{

void newCustomer(int seats[],boolean occupied[],String names[],int seat,String name) //Checks if seat is available for a new customer
{
int pos=-1;
