IN JAVA CODING You operate a restaurant and have a menu of items to offer your customer. A program is needed to take online orders for your food orders. You offer four entrees and two different side items. A customer first orders the total number of each entre that they want, and then they can choose side items.

Entrees Price

Salmon $18.00

Chicken $12.25

Steak $19.89

Lamb $15.59

Sides Price

Fries $ 2.99

Salad $ 4.99

The program that is needed for the online ordering system will allow the customer to order as many of each entree as they wish. They are then asked how many of each side they wish. It should ask for each side item at a time. When completing an order, an itemized bill is to be displayed. This bill should include a 7% sales tax and 10.0% service fee that applies to the subtotal, before taxes.

The Order Class (Order.java):

Instance variables: integer variables to store the counts for each of the menu items. Include double constant variables for the cost of each entre and each side. Also, include double constants for the tax rate and service charge rate. This class has the following methods:

Methods:

• Getters and setters for all instance variables.
• Constructor - the constructor should pass the counts for each of the menu items collected
• calculateSubTotal(): This method should calculate what the cost of the entrees are. It should return the subtotal.
• calculateTax(): This method should calculate tax given the subtotal.
• calculateServiceCharge(): This method should return service charge given the subtotal.
• calculateTotalCharge(): This method should receive the subtotal, tax and service charge and return the final total.
• toString(): See the summary below in the sample run to define the output

The Driver Class (Restaurant.java):

The driver class takes care of the following:

Input:

Your program will start by asking the user how many of each entre item they want. It will then proceed to ask the user to choose how many of each side item they want. Once all the items have been selected, instantiate an object and pass in these values.

Output:

Print the title, a line with each food item and the number of each item purchased, a subtotal of the cost of the items ordered, tax, delivery charge, and the total using the toString method.
