Code Snippet:

==============================================


// Interface: Defines the contract for all payment methods
interface Payment {
void process(double amount); // Every payment type must implement this
}
// CreditCardPayment: Implements the payment interface
class CreditCardPayment implements Payment {
@Override
public void process(double amount) {
System.out.println("Processing credit card payment of $" + amount);
}
}
// PayPalPayment: Implements the payment interface
class PayPalPayment implements Payment {
@Override
public void process(double amount) {
System.out.println("Processing PayPal payment of $" + amount);
}
}
// PaymentService: User-facing service to initiate payments
class PaymentService {
private Payment payment; // Holds a reference to the Payment interface
PaymentService(Payment payment) {
this.payment = payment; // Inject specific payment type
}
void makePayment(double amount) {
payment.process(amount); // Delegate processing to the implementation
}
}
public class Main {
public static void main(String[] args) {
// Using Credit Card payment
PaymentService service = new PaymentService(new CreditCardPayment());
service.makePayment(100.00);
// Using PayPal payment
service = new PaymentService(new PayPalPayment());
service.makePayment(200.50);
}
} ==============================================


// Abstract Class: Provides shared functionality and a structure
abstract class AbstractPayment {
void validatePayment() {
System.out.println("Validating payment details...");
}
abstract void process(double amount); // Subclasses must implement this
}
// CreditCardPayment: Extends AbstractPayment
class CreditCardPayment extends AbstractPayment {
@Override
void process(double amount) {
validatePayment(); // Reuse common functionality
System.out.println("Processing credit card payment of $" + amount);
}
}
// PayPalPayment: Extends AbstractPayment
class PayPalPayment extends AbstractPayment {
@Override
void process(double amount) {
validatePayment(); // Reuse common functionality
System.out.println("Processing PayPal payment of $" + amount);
}
}
