Code a subclass named ExpressCard that inherits from the superclass CreditCard, which has two private data members: foreignFeeRate of double type, and domesticBonusMileageRate of double type Provide: default constructor with no parameters, constructor with all parameters to initialize its own private data and the inherited data from CreditCard getter/setter methods for each data member There are two effector methods: Method calcFee() takes no parameters and it returns double type. This method calculates the transaction fee. First you need to call the method in superclass to obtain the basic fee, and then for ExpressCard user, there is an extra charge for foreign spending. Given the same example above as in class CreditCard, the basic fee is $3, and under a foreignFeeRate of 3%, then the extra fee is calculated by multiplying $50 of foreign spending with 3% (0.03) of foreignFeeRate, which yields $50 *0.03 = $1.5, so the total fee is $3 + $1.5 = $4.5. Method calcMileage() takes no…
