JAVA OOP 2  Design a currency converter class whose instance will handle conversion of all currencies. A single instance of the new currency converter class you design here will handle all currencies. Instead of having specific conversion methods such as toDollar, toYen, and so forth, the new currency converter class supports one generic conversion method called exchange. The method has three arguments: fromCurrency, toCurrency, and amount. The first two arguments are String and give the names of currencies. The third argument is float.
