Question

4. RetailItem 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 program that creates three RetailItem
objects and stores the following data in them:

Answer 1

class RetailItem {

    private String description;
    private int unitsOnHand;
    private double price;

    public RetailItem(String description, int unitsOnHand, double price) {
        this.description = description;
        this.unitsOnHand = unitsOnHand;
        this.price = price;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public int getUnitsOnHand() {
        return unitsOnHand;
    }

    public void setUnitsOnHand(int unitsOnHand) {
        this.unitsOnHand = unitsOnHand;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }
}

class RetailItemTest {

    public static void main(String[] args) {
        RetailItem item1 = new RetailItem("Jacket", 12, 59.95);
        RetailItem item2 = new RetailItem("Designer Jeans", 40, 34.95);
        RetailItem item3 = new RetailItem("Shirt", 20, 24.95);
        System.out.println("Description Units on Hand Price");
        System.out.println("Item #1 " + item1.getDescription() + " " + item1.getUnitsOnHand() + " " + item1.getPrice());
        System.out.println("Item #2 " + item2.getDescription() + " " + item2.getUnitsOnHand() + " " + item2.getPrice());
        System.out.println("Item #3 " + item3.getDescription() + " " + item3.getUnitsOnHand() + " " + item3.getPrice());
    }
