Description: Invoicing System is a software (program) that shall be used to store different data like: Customer names. Item names and its prices. Items purchased by each customer. This software shall also generates invoices for each customer based on the items he/she purchased. Basic Requirements: The program shall read the data from a text file called input.txt that follows a specific pattern. If the file doesn't exist, print a message to let the user know what happened.- see Input file for more details. The program shall generate a text file as the output called print.txt" that contains the results of the commands written in the input file see print file for more details. The program shall load data dynamically from the given text file input.txt" and user is not involved in data entry. The Initial Procedure of the Program: You will use File I/O concepts to read given file [input.txt). Make sure the file exist or display a message that the file does not exist. The file consists of: 2 integers to determine array size for customer names, item names, item prices (see input.txt file]: The first number (4) in the file refers to the number of customers to be stored in the System (means, system shall accept ONLY FOUR customers name. The second number (10) refers to the number of Items name to be stored in the system ( means system shall accept ONLY 10 Items name] Note: Item prices shall be of same size as of item names. Create a Single Dimension Array to store customers name (See Table 1), and create a method that read all names of customers from given input.txt file and stored customer name in an array. Table 1. Customers information Customer Name Jawad_Ali Saif Abdulraheem Fatima_Mohamed Nada_Ali // array of type String for the customer name Create a Single Dimension Array to store Item names (See Table 2), and create a method that read all Items names from given input.txt file and stored Item name in an array. Table 2. Item Names information Item name Pen Pencil Book Keyboard Mouse Watch Toys Shoe Sunglass Perfume // array of type String for the Item names Create a Single Dimension Array to store Item prices (See Table 3), and create a method that read all Items prices from given input.txt file and stored Item price in an array. Table 3. Item prices' information Item prices 10.0 5.0 230.0 450.0 330.0 950.0 73.5 480.0 8900.0 750.0 // array of type double for the Item prices Create a 3-Dimentional array to store items purchased and how many such purchased by each customers as shown (See Table 6). Table 4. Customer purchase record stored in 3 Dimension Array invoice to Rook:230 how Many (Quantity) Item Index 2 index customer o Jawad Ali Saif Abdulraheem 2 Fatima Mohamed Invoice[1] how Many Quantity) 3 Nada_Ali Item Index Perfume 6 10 85 The 3- Dimensional array virtually link customer, Item and price arrays. Each customer has number of items he/she want to buy, so this 3 Dimensional array have different rows and columns based on the total items customer is buying, which of the items he/she purchased and how many of them as shown in above table 4 and figure 1 illustrates the structure of the 3D array. Nada Ali Fatima_Mohamed Saif Abdulraheem Jawad Ali Invoice[3] invoice[2] invoice[1] invoice[0] Figure 1 The structure of the 3D array Note All Commands must be implemented using separate methods. The commands you will have to implement are as follows: add_cutomer-Your program shall read customer names and store in an array to be used in the system.

Note: You have to add the items purchased details for each customer as per above explanation. (see input.txt/Table 4] and Think] // Method to do above task print Item details-Your program shall automatically generate report based on Total Items available in the system and save in the output file. (see print.txt] 1/ Method to Print item detail in the output file. search Item Watch-Your program shall automatically Search the item based on name in the system and save in the output file. (see print.txt] // Method to search the item and its detail in the output file. In above line search_item is a command and Watch is the item you are searching in the system. Make sure to display exact message in the output file if record found or not found. (see print.txt] print All Invoices - Your program shall automatically generate Invoices for all the customer with detailed report like items purchased along sub-total and grand total of the invoice. This shall also generate a unique invoice number for each invoice and save in the output file. Make sure to generate exact invoice as given. (see print.txt] // Method to generate Invoice number. (start with JED + any Radom number in range of 10000] // Method to generate name of customer as per given sample output. (remove ) Note: You shall create a supporting method String textSplit(String text) to return a text by removing char from the given text. For example given text to the method is lawad Ali and the method return Jawad Ali. // Method to generate Invoices of each customer with complete details of the items purchased, how many, total, grand total etc about App Your program shall automatically save information about you as per given hint([Your Full Name], write your full name), etc. in the output file. Make sure to generate exact information, only replace it with your record. (see print.bct + Quit-This option will be used to Exit from the System. Output File Pattern The output file should include all the results of the commands that have been read from the input file [input.txt]. Your program must generate output in a similar format to the given sample output file [print.txt). All report are formatted save as per given sample output. Deliverable You have to submit only the java file of your code. The file and the class name should be "P1_Section_Your FirstName_YourID". Where Section is your class section. Your FirstName is your first name. You ID is your university ID. For example Pl_IT_Ahmad 199090. Important Notes: Your Code, output, results etc. must be in a readable form. Organize your code in separate methods. Repeat the program until Quit command is read by your program. Use comments in your code. Use meaningful variables. Use dash lines separator between each method. Description: Invoicing System is a software (program) that shall be used to store different data like: Customer names. Item names and its prices.
