ProductTester Class Driver

The ProductTester class is our main driver. It demonstrates how the entire system works using the Product, Category, and PasswordLockable implementations. Let’s walk through what this class is doing and why:

1. Creating the Product List

We first create an array of Product objects and store four sample products in it. Each product has a code, a description, a price, and a category.

Product[] productList = new Product[4];
productList[0] = new Product("A001", "Chicken", 72.45, Category.MEAT);
productList[1] = new Product("B002", "Milk", 22.35, Category.DAIRY);
productList[2] = new Product("C003", "Apples", 22.35, Category.PRODUCE);
productList[3] = new Product("D004", "Beef", 89.99, Category.MEAT);
