HELP IN JAVA:

This assignment mimics the configuration and the activities happen at a typical restaurant. Configuration file tables.txt contains the table information & menu.txt contains the full menu list (sample files have been attached).

We will use the following classes to complete this assignment. Feel free to add more variables if needed. Avoid making drastic changes to existing variables. You need to define the classes and implement all the .java files including class implementation and the overall application functionality.

Table : status, # of max seats, # of guests if a party is seated, order if the party has ordered

MenuItem: itemCode, name, price

Menu : array of MenuItems

Order : a list of menu items ordered at a table

Sample configuration file (config.txt)

Tables: table #, max seats

1 2 2 4 3 2 4 2 5 2 6 4 7 6 8 10 9 2 10 4 11 4 12 4 13 4 14 2 15 2 16 2 17 2 18 2 50 20

Menu: listing of the full menu: item code, name, price

A1 Bruschetta 5.29 A2 Caprese_Flatbread 6.10 A3 Artichoke-Spinach_Dip 3.99 A4 Lasagna_Fritta 4.99 A5 Mozzarella_Fonduta 5.99 E1 Lasagna_Classico 6.99 E2 Capellini_Pomodoro 7.99 E3 Eggplant_Parmigiana 8.99 E4 Fettuccine_Alfredo 7.49 E5 Tour_of_Italy 14.99 D1 Tiramisu 2.99 D2 Zeppoli 2.49 D3 Dolcini 3.49 S1 Soda 1.99 S2 Bella_Limonata 0.99 S3 Berry_Acqua_Fresca 2.88

Read the configuration file and create the necessary objects / array of objects, then proceed to read the activities from the user and process them one at a time. Do not use any advanced data structures that have not been covered in the class.
