Objective

To build a complete working Java program to apply variations on the selection control structure and basic

error$-$testing.

Overview & Instructions

Write a program that manages the rewards program for a credit card company.

Your program will prompt the user $($via dialog boxes$)$ for four data items. First, prompt for the following

three $($monetary decimal$)$ values related to monthly purchases made:

$$ Electronics $($Computers$,$ phones, tablets, etc.$)$

$$ Travel $($Gasoline$,$ air travel, etc.$)$

$$ General purchases

Next, prompt for one more $($single character$)$ data element:

$$ B or b $-$ for business

$$ P or p $-$ for personal

The initial rewards to be returned to the customer will be based on the following:

Type Reward Level

Electronics $3\%$

Travel $2\%$

All General $1\%$

This initial base reward amount to return will be these simple percentages multiplied by the respective

purchase amounts.

Next, offer all personal customers a volume reward based on the total monthly purchases using the

following scheme:

If total purchase amount is $...$ Additional reward is $...$

Over $$1000$ but under $$30001\%$

$$3000$ to $$50002\%$

above $$50003\%$

For business customers, travel and electronic purchases are being promoted so the following scheme

defines the volume reward:

If sum of travel and electronic

purchases is $...$

Additional reward is $...$

Over $$5,000$ but under $$7,5000\mathrm{.}5\%$

$$7,500$ to $$10,0001\%$

above $$10,000$ but not over $$100,0002\%$

Over $$100,0005\%$

Note that these additional volume awards are applied to the total monthly purchases of all categories and

are then added to the initial rewards calculated by category.

Finally, a "random drawing" is to be included for personal customers only. Every $5$th customer will

receive a $$25$ reward. Your program is only processing one customer at a time, so to simulate this

"drawing" a random number generator action must be included in your code to check for "one chance in

five". If this chance selection matches, add $$25$ to the total reward.

Your program should include the following error$-$checking features:

$$ Purchase amounts $($electronics$,$ travel, and general$)$ must all be zero or above

$$ Customer code must be only B or P

For input validation, work to utilize $"$if$"$ and "else" actions to bypass calculations and output for invalid

user input. Avoid use of multiple "exit points" within your program $($i$.$e$.$ using System.exit$(0)).$

Your output should be a clear, organized summary that includes the amount purchased in each category

$($i$.$e$.$ the input values$),$ the base reward amount, the additional reward total, the reward received from the

random drawing $($but only if received$),$ and final total reward. It should be formatted to dollar amounts

labels and headings as appropriate.

Finally, a programming note for String usage:

$$ Instead of if $($aString $=="$B$")$ use if $($aString$.$equals$("$B$"))$

$$ To convert a String to a char, use: aChar $=$ aString.charAt$(0)$;
