Modify the Inventory Program:


Create a new method that calculates the value of the entire inventory.

Create another method that sorts all of the array items alphabetically (ascending order) by the product name.

o The application should declare and use an array to store 5 items. This array will represent your product’s inventory.

o Create a subclass of the selected inventory item. Recall that the extends keyword is used to create an inheritance relationship.

 The subclass and existing class must past the is-a test.

 The subclass must declare one applicable attribute along with the appropriate get and set methods.

 The subclass must declare a method to calculate the restocking fee. The restocking fee should be calculated as 5% of the item’s price.

o The application’s output should display all of the items in the inventory sorted (use the new sort method) and include the item number, the name of the product, the number of units in stock, the price of each unit, the new attribute, the restock fee and the value of the inventory of that product. In addition, the output should display the value of the entire inventory (use the new method to achieve this). All dollar values should be displayed as currency (i.e. $D,DDD.CC). Note: You must use an Array to store your inventory items, the use of any other data structure will result in a significant point deduction.


I think the code I have written for the object is correct, Monitors.java, but I will include it as well.

// Monitors.java
// Inventories monitors by the item number, the name of the product,
// the number of units in stock, and the price of each unit for the

	{
	private int idNumber;
	private String productName;

	private double productPrice;
	public String storeName;

		public Monitors (int number, String name, int count, double price)

			this.setProductCount(count);
			this.setProductPrice(price);
