Write a program that reads customers information from a

Question

Write a program that reads customers' information from a file, and creates a movie theatre seating with a number of rows and columns specified by a user. Then it will attempt to assign each customer to a seat in a movie theatre.

You will be creating a class called MovieSeating. This class should be defined in a file named MovieSeating.java. The class MovieSeating will contain a 2 dimensional array called seating of Customer objects as its instance variable.

The last file is an input file (text file) that will be read from the Assignment7 class. Save all of the files in the same folder.

The class MovieSeating must include the following constructor and methods. (If your class does not contain any of the following methods, points will be deducted.)

 public MovieSeating(int rowNum, int columnNum) - It instantiates a two dimensional array of the size rowNum by columnNum specified by the parameters. Then it initializes each customer element of this array using the constructor of the class Customer without any parameter. So each customer will have default values for its instance variables.

 private Customer getCustomerAt(int row, int col) - It returns a customer at the indexes row and col (specified by the parameters of this method) of the array seating.


public boolean assignCustomerAt(int row, int col, Customer tempCustomer) - The method attempts to assign tempCustomer to the seat at row and col (specified by the parameters of this method). If the seat has a default customer, i.e., a customer with the last name "???" and the first

name "???", then we can assign the new customer tempCustomer to that seat and the method returns true. Otherwise, this seat is considered to be taken by someone else, the method does not assign the customer and returns false.

 public boolean checkBoundaries(int row, int col) - The method checks if the parameters row and col are valid. If at least one of the parameters row or col is less than 0 or larger than the last index of the array (note that the size of rows and columns can be dierent), then it returns false.

Otherwise it returns true.

 public String toString() - Returns a String containing information of the seating. It should show the list of customers assigned to the seating using the toString method of the class Customer (it shows initials of each customer) and the following format:

The current seating
