Objective:

Develop a program that allows users to input inventory data. The program should continuously prompt the user to enter the name and price of each item until they decide to stop. Once the data collection is complete, the program will display the complete inventory and total price of all items in the inventory list.

$$

Requirements:

$1.$ Class $-$ Inventory

$$ Create a Class named $$Inventory$$

$$ Define a private String variable for the item name.

$$ Define a private double variable for the item price.

$$ Implement a no$-$argument constructor that initializes the item name to null and the price to $0\mathrm{.}0.$

$$ Implement a constructor that accepts parameters for both the item name and price.

$$ Create accessor $($getter$)$ methods for both the item name and price.

$$ Create mutator $($setter$)$ methods for both the item name and price.

$2.$ Class $$ Demo

$$ Demonstrate the functionality of the Inventory class in a separate class called Demo.

$$ Create an ArrayList to store instances of Inventory items.

$$ Instantiate at least three Inventory objects and add them to the ArrayList.

$$ Prompt the user to enter item names and prices, adding each item to the ArrayList until they choose to exit.

$$ Implement a method to get the total price for all items in the Inventory

$$ Display the price to the user

$3.$ Input Validation

$$ Implement functionality to allow users to input case insensitive values to quit the program

$4.$ Output

$$ Print the item names along with their corresponding prices.

$$ Ensure that all prices $($item and total purchase price$)$ are displayed with two decimal places.
