Develop a Java Program to Model a Currency Conversion System Write a Java program of handling purchase orders by fulfilling the following requirements, which includes two classes: CurrencyConverter, and AskCurrencyConverter.

• This assessment work may not reflect a real and complete scenario in actual cases.

1. Class CurrencyConverter [14 marks] o Create a public Java class CurrencyConverter, in file CurrencyConverter.java, to model Currency Conversion based on the given UML, the naming and the descriptions below: o The class 代写SOUL-Quiz Feature CurrencyConverter has three fields, representing data information, as the field names and types in the UML class diagram. o 1) Exchange rate

2. Commission rate
3. Threshold amount of money o One public constructor which accepts 2 input parameters which simply sets its fields with these input parameters accordingly. o A related method converts US dollars to foreign currency: If amount is greater than or equal to the threshold amount, applies half commission rate If amount is less than the threshold amount, applies full commission rate Formula: dollar × exchangeRate × (1 - commission) o A related method converts foreign currency to US dollars: If equivalent USD amount is greater than or equal to the threshold amount, applies half commission rate If equivalent USD amount is less than the threshold amount, applies full commission rate Formula: foreignMoney ÷ exchangeRate × (1 - commission) o A related method sets/gets the exchange rate between USD and foreign currency. o A related method sets/gets the commission rate charged for conversion. o A related method sets/gets the threshold amount for reduced commission. CurrencyConverter
   • exchangeRate: double

• commissionRate: double
• largeAmount: int
  • CurrencyConverter (er: double, cr: double)

• fromUSDollar(dollar: double): double

• toUSDollar(forignMoney: double): double

• setExchangeRate(rate: double) +getExchangeRate(): double

• setCommissionRate(rate: double)

• getCommissionRate(): double

• setLargeAmount(amount: int)

• getLargeAmount(): int 2/3

  Class AskCurrencyConverter [6 marks] o Create a public Java class AskCurrencyConverter, in file AskCurrencyConverter.java, as the main class of the Currency Conversion System based on the description below. o Instantiate two CurrencyConverter objects with the following attributes: exchangeRate commissionRate yenConverter 115.7 0.0005 euroConverter 0.9927 0.0003 o Set largeAmount to US$50000. o Use the yenConverter to convert 1500000 yens to US dollars. o Use the yenConverter to convert from US$2000 to yens. o Set the exchange rate of euro to 0.9881. o Use the euroConverter to convert 170000 euros to US$. o Use the euroConverter to convert from US$20000 to euros. Sample Program Output --- Currency Conversion System, A2, OOP, 2024 *** 1500000 yens = US$12958.0812445981 US$ 2000 = 231284.30000000002 yens 170000 euros = US$172021.55652261918 US$ 20000 = 19756.0714 euros
