This program has to start with the source code:

//Driver.java public class Driver {

public static void main(String[] args) { // TODO Auto-generated method stub FileIO a1 = new FileIO("Z:\\JavaPrograms2\\assignment336b\\src\\Salesdat.txt"); Franchise f = a1.readData(); }

}

//FileIO.java

import java.io.*; import java.util.*;

public class FileIO { private String fname = null; private boolean DEBUG = true;

public FileIO(String fname) { this.fname = fname; }

public Franchise readData() { Franchise a1 = null; int counter = 0; try { FileReader file = new FileReader(fname); BufferedReader buff = new BufferedReader(file); String temp; boolean eof = false; while (!eof) { String line = buff.readLine(); counter++; if (line == null) eof = true; else { if (DEBUG) System.out.println("Reading" + line); if (counter == 1) { temp = line; a1 = new Franchise(Integer.parseInt(temp)); if (DEBUG) System.out.println("d " + a1.numberofstores()); } if (counter == 2) ; if (counter > 2) { int x = buildStore(a1, (counter-3), line); if (DEBUG) System.out.println("Reading Store # "+(counter-2)+" Number of weeks read = " + x); if (DEBUG) { System.out.println("Data read:"); a1.getStores(counter-3).printdata(); } } } } buff.close(); } catch (Exception e) { System.out.println("Error -- " + e.toString()); } return a1; }

public int buildStore(Franchise a1, int counter, String temp) { Store tstore = new Store(); String s1 = ""; float sale = 0.0f; int week = 0; int day = 0; StringTokenizer st = new StringTokenizer(temp); while (st.hasMoreTokens()) { for(day=0;day { s1 = st.nextToken(); sale = Float.parseFloat(s1); tstore.setsaleforweekdayintersection(week, day, sale); } week++; } a1.setStores(tstore, counter); return week; } }

//Franchise.java

public class Franchise { private Store stores[]; public Franchise(int num) { stores = new Store[num]; }

public Store getStores(int i) { return stores[i]; }

public void setStores(Store stores, int i) { this.stores[i] = stores; } public int numberofstores() { return stores.length; } }

Write a program that opens the following text file and processes its contents. The program should display the following per store:

• The total sales for each week. (Should print 5 values - one for each week).
• The average daily sales for each week. (Should print 5 values - one for each week).
• The total sales for all the weeks. (Should print 1 value)
• The average weekly sales. (Should print 1 value)
• The week with the highest amount in sales. (Should print 1 week #)
• The week with the lowest amount in sales. (Should print 1 week #)

The file contains the dollars amount of sales that a retail store made each day for a number of weeks. Each line in the file contains thirty five numbers, which are sales numbers for five weeks. The numbers are separated by space. Each line in the file represents a separate store.

Please make sure that you:

1. Add a design and class diagram with your submission.
2. Add comments to your code in FileIO class.
3. Make sure you adequately test your code.
4. Provide a user-friendly interface (Console based) in a separate class called UI.java

Before submitting your work, please reflect on following points:

1. No errors, the program always works correctly and meets the specification(s).
2. User interface class is provided to interface with Sales Application - Design for this provided in lecture.
3. The code could be reused as a whole or each routine could be reused.
4. Concepts of Array of Objects and Text File Input/Output are applied.
5. Java coding conventions are followed.
6. Code Readability (as suggested in class)
7. Adequately tested (unique test cases, covering boundary conditions)
8. Class diagram is provided (UML usage is not required)
