Type-specific Processing method with instanceof

In this problem, you will create a program that uses the instanceof operator to identify the actual type of a Payment object (CashPayment, CardPayment, or PointPayment), performs different processing for each subtype in a single process(Payment) method, and displays the result to standard output.

Learning Objective: Design a method that performs different processing based on object type using instanceof

Overview

Create a method that receives parent class type as parameter and performs different processing based on actual type.

Specifications

• Define Payment class and its subclasses (CashPayment, CardPayment, PointPayment)
• Implement process(Payment) method in PaymentProcessor class
• Read payment information from standard input, process according to payment method, and output result

Input Format

cash amount (integer)
card amount (integer) card number (16-digit string)
point amount (integer)

Input Example

1000
2500 1234567890123456
500

Output Format

Processing cash payment: 1000 yen
Processing card payment: 2500 yen (Card: 1234-****)
Processing point payment: 500 points
