Question

IN JAVA PLEASE Design and implement an ADT CreditCard that represents a credit card. The data of the ADT should include Java variables for the customer name, the account number, the next due date, the reward points, and the account balance. The initialization operation should set the data to client-supplied values. Include operations for a credit card charge, a cash advance, a payment, the addition of interest to the balance, and the display of the statistics of the account. Be sure to include a main class which creates an object from your CreditCard class.

I would really apreciate if you can walk me through it and provide me a full soluition of how to implement the code. Everything is stated in the question

Here is what I have so far I get a blank when I run the program...

public interface CreditCard {
public static void main(String[] args) {
}

String name = "";
String accountNumber = "";

String dueDate = "";

int rewardPoints = 0;
double accountBlance = 0.0;

public boolean inputCreditCard(String name, String accountNumber);

public boolean chargeCreditCard(String accountNumber, double charge);

public boolean getCashAdvance(String accountNumber, double advance);

public boolean submitPayment(String accountNumber, double payment);

public double combineIntrest(String accountNumber);

public void displayStatistics(String accountNumber);

}
