Design and implement a program to quote currency exchange rates for different currencies from different banks. The advantage is the firm's clients can get the best rates on foreign currency when traveling. Problem Description Our project requires us to define Banks. Each Bank can exchange three currencies to and from US dollars. For each currency, there is a rate at which the bank will buy and sell the currency in exchange for US dollars. In addition, the bank charges a commission as a fee for performing the exchange. All of this information is specified in a text file for each bank, which will be in the following format: bank name commission rate currency_code exchange_rate currency_code exchange_rate currency_code exchange rate As an example, consider these two banks: Bank1.txt: Duskull Bank 0.11 EUR 0.89 AUD 1.41 RUB 64.85 Bank2.txt: W D'Focus Aseel Batuq 62F Light rain M ox Comments Share 4) 110% 1:11 PM 3/30/2022 11 x 98 W AutoSave Off CS160Project3 (1) Protected View Saved to this PC File Home Insert Draw Design Layout References Mailings O Search (Alt+Q) Review View Help i PROTECTED VIEW Be careful-files from the Internet can contain viruses.

After reading the bank information, your program should prompt the user to enter the type of transaction ("buy" or "sell") the currency code (e.g., "EUR" or "eur" or "Eur") the amount of the foreign currency to buy or sell Then the program will display quotes from the two banks for the proposed currency exchange. All of this input and output happens in the console. Here is an example which defines the messages you should print (output is in normal font, input is bold font) and how you should handle incorrect input: Do you want to buy or sell? what Please try again. Do you want to buy or sell? buy Which currency? POKE I'm sorry, There is no bank that can exchange POKE. Please start again. Do you want to buy or sell? sell Which currency? jpy There is one bank that can exchange JPY. How many JPY? 4858.28 Felicity Bank will give you 30.78 USD for 4858.28 JPY, after collecting a commission of 13.19 USD (30%) Do you want to perform another transaction? yes Do you want to buy or sell? buy Which currency?

How many EUR? 1000 Duskull Bank will give you 1000.00 EUR for 1247.19 USD after collecting a commission of 123.60 USD (11%) Felicity Bank will give you 1000.00 EUR for 1368.42 USD after collecting a commission of 315.79 USD (30%) Do you wish to perform another transaction? no Have a nice day.

The commission percentage is rounded to the nearest whole percent. The currency code is always printed in UPPER CASE as it appears in the bank file. The user's input should be accepted with any capitalization they wish, though. Project Requirements The requirements for this project are provided as a list of classes that must be created in your implementation of the project. This is your first project writing your own classes and making objects of them. You may add other methods not included here if you desire, but your code must include the following classes with the specified methods: Page 2 of 5 1722 words O Text Predictions: On Links CS160 Introduction to Computer Science I Spring 2022 Currency Class (10 points) Each currency line in the bank data files will be translated into an object instance of the Currency class that should contain the following: [2 pts] Two private data fields, one to hold the currency code and one to hold the exchange rate. Remember that the exchange rate for the same currency can be different for different banks. [4 pts] A constructor that takes two arguments: the currency code and exchange rate. The constructor should assign the value of the private members from the values of the arguments. [2 pts] An accessor method for each data field. [2 pts] A mutator method for each data field.

[8 pts] Read the bank information from the file and use it to initialize all of the bank's data fields. [5 pts] A method called supportCurrency that takes a currency code (a String) as its only argument. It should return true if the bank can exchange the given currency and false if it cannot. [5 pts] A method called getRate that takes a currency code (a String) as its only argument. It should return the rate of exchange for that currency, or -1.0 if the bank does not exchange that currency. Two methods: quoteBuy and quoteSell. Both methods takes two arguments: a String for the currency code and a double for the amount of foreign currency. Each method will return a Quote object (defined below) if the bank supports that currency and null if the bank does not. Call the getRate method you wrote within your quote methods. Use the following formulas to calculate the number of US dollars and the bank's commission: For selling amt units of currency with exchange rate exchRate, the number of US dollars before commission is amt / exchRate; call that result base. Then the commission is the commission rate comRate (between 0.0 and 1.0) times base and the amount of US dollars the customer will be paid is base minus the commission. base = amt / exchRate commission = comRate * base totalPay = base - commission W Aseel Batuq Focus 62F Light rain M ox Comments Share 110% 1:12 PM 3/30/2022 11 x L W AutoSave Off CS160Project3 (1) Protected View Saved to this PC File Home Insert Draw Design Layout References Mailings O Search (Alt+Q) Review View Help i PROTECTED VIEW Be careful-files from the Internet can contain viruses.

Commission rate charged by the bank. o Dollar amount of the commission. o A DecimalFormat object for formatting currencies (i.e., two digits after the decimal point). [5 pts] A constructor that takes 7 arguments, corresponding to the first 7 data fields listed above. The constructor should set those fields from the values of the arguments and create the DecimalFormat object. [7 pts] A method called toString that takes no arguments and returns a String. It should return the message that will be printed out for the quote, as listed above (i.e., "Shady Airport Bank will give you 1000.00 CAD for 843.91 USD, after collecting a commission of 168.78 USD (20%)"). The commission amount should always be reported in US dollars.
