Question set 5: ( Java ) Object Oriented-

1. Create a class called Car. The class should have the following three instance variables: make(String), speed(double), and year(String). Write a constructor to allow objects to be created with these three initial values. Also write all the getter, setter and toString() methods. Write a Demo class to create three Car objects with some meaningful initial values and display them using the toString()method.

2. Create a class called Order. The class should include the following three fields:a.Item description (e.g., Beef Skillet)b.Quantity (e.g., 1 or 2, etc.)c.Unit price (e.g., 9.99)

Write a Demo class. In this Demo class, you will create at least the following four methods:a.showMenu():It will display a Restaurant menu sort of like the one shown below.b.create Order():It will allow the user to pick menu items (e.g., E2) and quantity using a Scanner object. Each item and its quantity picked, together with its unit price, will be used to create an Order object. A user can pick as many items as he/she wants. This will create an equal number of Order objects. These Order objects will be stored in an array as they are created.c.showCheck(): It will display a receipt based on the orders made by the user. It will show something like the following
