Problem Description

List Management: Shopping List

In this problem, you will create a program that reads product names from standard input, stores them in an ArrayList, displays each item with a numbered label, and outputs the total count to standard output.

Learning Objective: Use ArrayList to manage multiple data and learn basic operations of add, get, and size

Read the number of products and each product name from standard input, storing them in an ArrayList<String> using add(). Then iterate over the list with a for loop, retrieving each element via get(i) to display it in [1] product name format, and finally output the total item count using size().
