Problem Description

Map Management: Product Price List

In this problem, you will create a program that uses LinkedHashMap to store product names and prices in insertion order, and displays a price list with the total amount to standard output.

Learning Objective: Use key-value pairs with LinkedHashMap to manage correspondence between product names and prices

Create a price list program that manages product names and their prices. Declare a LinkedHashMap<String, Integer> and register each product using put(productName, price). After all products are registered, iterate through entries with entrySet() to display them in insertion order, then use values() to retrieve all prices and calculate the total amount.

Output

Price List:
[product name 1]: [price 1]yen
[product name 2]: [price 2]yen
...
Total: [total amount]yen
```java

Products displayed in registration order.
