You are shopping for a grocery item. Supermarkets often give prices for a group of items, such as 5 for $1.25 or 3 for $1, instead of the price for one item. The possibility is if they price apples at 5 for $1.25, you will buy 5 apples instead of 2. But 5 for $1.25 is $0.25 each. So, if you buy 2 apples, they charge you only $0.50.

Write a Java class called Grocery that will handle the total price. Use the following UML diagram.

Class

Grocery

Attributes

nameOfItem : String

unitCost: double

totalCost: double

Methods

Grocery(String item)

processItem(int groupCount, double groupPrice, int quantity) : void

display() : void

The names of the variable and methods indicate their functionality.

• Use the constructor of class to initialize the name of item to purchase.
• Use the processItem method to keep track of the total price.
• The total price of the purchase is calculated here.
• Use the display method to print the item name, unit cost and total price to the console.

In a tester class that holds a main method, perform the following tasks

• Create a Scanner object.
• Use the appropriate Scanner method/calls to take name of item.
• Create a Grocery object.
• Use the appropriate Scanner method to take group count and group price following by quantity.
• Call processItem method.
• Call display method.

Your output should be similar to this:

Enter name of item you are purchasing:

cucumbers

Enter price of item as two numbers.

For example, 4 for $2.99 is entered as

4 2.99

Enter price of item as two numbers, now:

6 8.47

Enter number of items purchased:2

You bought: cucumbers

Cost each: $1.41

Total cost: $2.82
