Objective

To build a complete working Java program that applies control structures and file processing.

Overview & Instructions

Write program that builds a summary of electronic sales. DeltaComputing is a manufacturer of popular

ePhone, ePads, and eWatches. The company also sells their products to wholesale customer.

Primary product costs are: ePhones: $$499\mathrm{.}99$; ePads: $$399\mathrm{.}99$; and eWatches are $$299\mathrm{.}99.$ In addition,

DeltaComputing sells a high$-$end computer $($an ePC selling for $$2999\mathrm{.}99),$ but ePC units are only available

to business$/$government customers.

Sales requests are "batched" daily within an input file for processing. The file for today can be found at the

provided link: eOrders.txt$.$ The file is 'white$-$space tokenized" in the follow format:

Sample data could be:

TimKling $0101$ Personal order for one ePhone and one eWatch

DeltaCollege $20300$ Non$-$profit order for $30$ ePads

PioneerElectronics $114398223$ Business order for $143$ ePhones, $98$ ePads, $22$

eWatches, and $3$ ePCs

The customer type codes are: $0-$ General general or individual customer

$1-$ Business or government customer

$2-$ Non$-$profit customer $($tax$-$exempt$)$

Your program should read sales data line$-$by$-$line and generate a sales cost summary for each line. Assume

the input file is consistently tokenized allowing general input strategies available with the Scanner class.

Further assume an unknown number of orders in the file. Allow the end$-$of$-$file indicator to terminate the

program.

Important: Note that the number of data tokens is not the same for all customer types. If a customer is a

business, there are four additional data tokens. Otherwise, there are three. This must be accommodated

within the line$-$by$-$line processing to keep the data synchronized with the processing loop.

Michigan sales tax $(6\%)$ is charged for all personal and business orders but not non$-$profit orders. Tax will

be charged on the cost of the order $($i$.$e$.$ be sure to calculate tax on the base charge $-$ i$.$e$.$ before discounts

and before shipping$).$

Shipping involves distribution of the electronic devices into boxes. To make shipping a bit easier, assume

$($unrealistically$)$ that all three product item have the same size of packaging. Shipping can then be

determined by the total number of items in an order and the number of and type of boxes needed to ship.

The boxes come in two sizes:

$$ a large box holds $20$ product items and costs $$19\mathrm{.}99$ to ship

$$ a small box holds $4$ product items and costs $$5\mathrm{.}99$ to ship

The order is shipped in the least expensive manner. The rule for packing is to fill the large boxes

completely; that is$,$ the box is fully packed. Only the small boxes can have empty spaces. For example, the

order of $54$ bags will be shipped in six boxes: two large, and four small $($with one small box not completely

full$).$

For high$-$volume customers, these shipping costs are reduced by $30\%$ if the total number of product items is

over $100.$ All non$-$profit orders receive free shipping.

Discounts are offered for the following circumstances:

$$ Any personal order that includes at least one ePhone, one ePad, and one eWatch receive a $5\%$

discount off of the product total $($before shipping$)$

$$ Any business$/$government order that totals over $$50,000$ receive $10\%$ discount on the product total

Your output should appear as an organized, formal financial report summarizing each order in detail. Write

your entire output report to either the console or an external file. This will preserve formatting and

alignment of the report. An example format could be:

Boxes

Customer Base Cost Discount Tax Shipping Total Sm Lg

xxxxxxxxx $xxxxx$.$xx $xxx$.$xx $xxx$.$xx $xxx$.$xx $xxxxx$.$xx xx xx

xxxxxxxxx $xxxxx$.$xx $xxx$.$xx $xxx$.$xx $xxx$.$xx $xxxxx$.$xx xx xx

$...$ and so on $...$

TOTALS $xxxx$.$xx $xxxx$.$xx $xxxxx$.$xx xxx xxx

Be sure all dollar amounts are formatted to two decimal places. After completing all output lines for each of

the orders in the input file, write totals at the bottom of your report for the tax, shipping, total, and box

columns. This implies accumulating the totals as you process them within the file loop and then writing

them after the loop completes.
