Write Java Classes please read what's asked and dont add unnecassary parts In this problem, you will create a shopping cart that will help a user keep track of bought items and their prices. To do so, you will first create an Item class, a ShoppingCart class and finally a driver class in which you will read items’ information from a text file and print the bill to the user. A. Item Class 1. The item class is defined by the following properties: a. Name. b. Price (Representing the unit price). c. Quantity (Representing the number of units). 2. Add a constructor that takes as argument the name, price and quantity of the food item. Initialize your variables accordingly. 3. You will need to retrieve all the properties of the class later on. Add the appropriate methods. 4. Add the following methods: a. A toString method that returns a properly formatted summary of the: name of the item, unit price (in U.S dollars) and the quantity as shown below: Bread 00.69$ * 3 b. A getTotalPrice method that returns the total price based on the items in the cart. B. Shopping Cart Class 1. The ShoppingCart class is defined by the following properties: a. An array of items to keep track of the items in the cart. b. Item count representing the number of items in the cart. c. Total Price representing the total price of cart based on the items. 2. Add a constructor that takes no arguments. Your constructor must initialize all your variables. Consider that the original capacity is 5 items. 3. Add the following method to your class: a. increaseSize: a method that increases the capacity of the cart by 3. The method must preserve the food items already stored. This method will only be called from within the ShoppingCart class. b. addToCart: a method that takes as argument an Item object and adds it to the cart. This method should also update all class variables accordingly upon the addition of an item. c. Since the item capacity is initialized to 5, you must make sure that the capacity is not full. If the cart is full, use the appropriate method to increase the size of the cart before adding the item. d. toString: the toString method should return a summary of the cart as shown in the sample below: Cart items: Bread 00.69 $ * 3 Cheese 01.24 $ * 2 Chicken 01.49 $ * 10 Total Price: 19.45 $

Write Java Classes

please read what's asked and dont add unnecassary parts

In this problem, you will create a shopping cart that will help a user keep track of bought items and their prices. To do so, you will first create an Item class, a ShoppingCart class and finally a driver class in which you will read items’ information from a text file and print the bill to the user.

A. Item Class

1. The item class is defined by the following properties:

a. Name.

b. Price (Representing the unit price).

c. Quantity (Representing the number of units).

2. Add a constructor that takes as argument the name, price and quantity of the food item. Initialize your variables accordingly.

3. You will need to retrieve all the properties of the class later on. Add the appropriate methods.

4. Add the following methods:

a. A toString method that returns a properly formatted summary of the: name of the item, unit price (in U.S dollars) and the quantity as shown below:

Bread 00.69$ * 3

b. A getTotalPrice method that returns the total price based on the items in the cart.

B. Shopping Cart Class

1. The ShoppingCart class is defined by the following properties:

a. An array of items to keep track of the items in the cart.

b. Item count representing the number of items in the cart.

c. Total Price representing the total price of cart based on the items.

2. Add a constructor that takes no arguments. Your constructor must initialize all your variables. Consider that the original capacity is 5 items.

3. Add the following method to your class:

a. increaseSize: a method that increases the capacity of the cart by 3. The method must preserve the food items already stored. This method will only be called from within the ShoppingCart class.

b. addToCart: a method that takes as argument an Item object and adds it to the cart. This method should also update all class variables accordingly upon the addition of an item.

c. Since the item capacity is initialized to 5, you must make sure that the capacity is not full. If the cart is full, use the appropriate method to increase the size of the cart before adding the item.

d. toString: the toString method should return a summary of the cart as shown in the sample below:

Cart items:

Bread 00.69 $ * 3

Cheese 01.24 $ * 2

Chicken 01.49 $ * 10

Total Price: 19.45 $

C. Driver Class

1. Copy and paste the information below in a text file called “Items.txt”

Item Unit price ($) quantity (100 grams)

Bread 0.69 3

Cheese 1.24 2

Chicken 1.49 10

2. Using the information in the text file create a ShoppingCart of Items.

3. Print a summary of the cart for the user.
