Retail Item Class
Write a class named RetailItem that holds data about an item in a retail store. The class should have the following fields:
- description. The description field references a String object that holds a brief description of the item.
- unitsOnHand. The unitsOnHand field is an int variable that holds the number of units currently in inventory.
- price. The price field is a double that holds the item’s retail price.
Write a constructor that accepts arguments for each field, appropriate mutator methods that store values in these fields, and accessor methods that return the values in these fields. Once you have written the class, write a separate

- 2. Car Class Write a class named car that has the following fields: ▪ yearModel. The year Model field is an int that holds the car's year model. ▪ make. The make field is a String object that holds the make of the car, such as "Ford", "Chevrolet", "Honda", etc. ▪ speed. The speed field is an int that holds the car's current speed. In addition, the class should have the following methods. ■ Constructor. The constructor should accept the car's year model and make as arguments. These values should be assigned to the object's year Model and make fields. The constructor should also assign 0 to the speed field.arrow_forwardINVENTORY CLASS You need to create an Inventory class containing the private data fields, as well as the methods for the Inventory class (object). Be sure your Inventory class defines the private data fields, at least one constructor, accessor and mutator methods, method overloading (to handle the data coming into the Inventory class as either a String and/or int/float), as well as all of the methods (methods to calculate) to manipulate the Inventory class (object). The data fields in the Inventory class include the inventory product number (int), inventory product description (String), inventory product price (float), inventory quantity on hand (int), inventory quantity on order (int), and inventory quantity sold (int). The Inventory class (java file) should also contain all of the static data fields, as well as static methods to handle the logic in counting all of the objects processed (counter), as well as totals (accumulators) for the total product inventory and the total product…arrow_forwardTrue or False Class fields are almost always declared public in order to make their values easily accessible to code outside of the class.arrow_forward

The idNumber is an int variable that holds the employee's ID number. • department. The department field references a string object that holds the name of the department where the employee works. • position. The position field references a string object that holds the employee's job title. The class should have the following constructors: • A constructor that accepts the following values as arguments and assigns them to the appropriate fields: employee's name, employee's ID number, department, and position. • A constructor that accepts the following values as arguments and assigns them to the appropriate fields: employee's name and ID number.

Example values are "Dog", "Cat", and "Bird". age: The age field holds the pet’s age. The Pet class should also have the following methods: setName: The setName method stores a value in the name setType: The setType method stores a value in the type setAge: The setAge method stores a value in the age getName: The getName method returns the value of the name getType: The getType method returns the value of the type getAge: The getAge method returns the value of the age Once you have designed the class, design a program that creates an object of the class and prompts the user to enter the name, type, and age of his or her pet. This data should be stored in the object. Use the object’s accessor methods to retrieve the pet’s name, type, and age and display this data on the screen. *** I need help…arrow_forwardPet ClassDesign a class named Pet, which should have the following fields: name: The name field holds the name of a pet. type: The type field holds the type of animal that a pet is.
