Some Helping Hints :

import java.util.Random;

import java.util.Scanner;

To get number from $1.\mathrm{.}5$

number$0$fItems $=$ randGen.nextInt$(5)+1$;

To get price from $0\mathrm{.}0$ to $50\mathrm{.}0$

itemPrice $=$ Math.round$($randGen$.$nextDouble$()*50*100\mathrm{.}0)/100\mathrm{.}0$;

To format to $2$ decimal places

System.out.printf$("$Total Price Paid: $\%2\mathrm{.}02\frac{f}{?}$

$,$ totalPrice$)$;

Write a program that simulates the activity at a grocery store.

Each customer has a grocery list, fills their shopping cart and chooses a cash register.

Print the customer number, item number and cost, cash register used, total price and average price per item paid.

Assume the following declarations:

Scanner scnr $=$ new Scanner$($

System.in$)$;

Random randGen $=$ new Random $($

Get the number of cash registers $($numberOfCashRegisters$)$ using scnr$.$nextInt$(4)$

Get the number of customers $($numberOfCustomers$)$ using scnr$.$nextInt$(5)$

For each customer:

$3\mathrm{.}1.$ Get the number of items $($numberOfItems$)$ in grocery list using randGen.nextInt$(5)$

$3\mathrm{.}2.$ For each item in grocery list $(0..$ numberOfItems$)$

$3\mathrm{.}2\mathrm{.}1.$ Get its price using randGen.nextDouble$()$

$3\mathrm{.}2\mathrm{.}2.$Print the item number and price

$3\mathrm{.}2\mathrm{.}3.$Add this price to total price paid so far

$3\mathrm{.}3.$ Get register to checkout using scnr$.$nextInt$($numberOfCashRegisters$)$

$3\mathrm{.}4.$ Print the following:

$3\mathrm{.}4\mathrm{.}1.$ Cash register used

$3\mathrm{.}4\mathrm{.}2.$ Total price paid at register

$3\mathrm{.}4\mathrm{.}3.$Average price of items bought

For the above, every time you see Get $($in bold$)$ it means the value is printed on its own line with the exception of:

The price for each item in the grocery list, these are printed all on one line, separated by spaces

All floats are printed to $2$ decimal places.

All code can be in main$()$ you do not have to break this up into separate methods$/$functions$,$ but you may if you want.

There should be no more than:

$4$ cash registers

$5$ customers

$5$ items in a grocery list

$50$ as a price of an item in the grocery list

User input must be checked for number of cash registers $(4)$ and number of customers$(5)$
