- Class CurrencyConverter [14 marks]o
Create a public Java class
CurrencyConverter, in fileCurrencyConverter.java, to modelCurrency Conversion based on the giveUML, the naming and the descriptionsbelow:oThe class CurrencyConverter hasthree fields, representing data information,as the field names and types in the UMLclass diagram.o
1) Exchange rate
- 2) Commission rate
- 3) Threshold amount of money
oOne public constructor which accepts 2input parameters which simply sets its fieldswith these input parameters accordingly.oA related method converts US dollars to foreign currency:If amount is greater than or equal to the threshold amount, applies half commission rateIf amount is less than thethreshold amount, applies full commission rateFormula: dollar × exchangeRate × (1 - commission)oA related method converts foreign currency to US dollars:If equivalent USD amount is greater than or equal to the threshold amount, applies half
commission rateIf equivalent USD amount is less than the threshold amount, applies full commission rateFormula: foreignMoney ÷ exchangeRate × (1 - commission)oA related method sets/gets the exchange 代寫 A2A (SOUL-Quiz Feature rate between USD and foreign currency.o
