For Java: Create a program that simulates a vending machine your program will ask the user to enter a price for an item first, then enter the amount of money deposited. Your program should display the change that is given to the user, as a number of quarters, dimes, nickels, and pennies. Change should be given using the smallest number of coins possible (change higher than 1 dollar can be given in quarters). If the user will receive no change, say no change instead of 0 quarters, 0 dimes, 0 nickels and 0 pennies. If the user enters less money than the price of the item then give an error message stating not enough money inserted with an error icon. After each transaction, whether enough money or not, ask the user if they have another transaction, using yes and no buttons, and repeat if so. Use JoptionPane for all inputs/outputs (no Scanner or println). Note: You can assume that the user will type the price as a decimal number without a dollar sign. Note: Rounding errors within a penny are OK.

Sample inputs/outputs (note shown here in text, but should all be through JoptionPane):

Enter price of item: $1.25

Enter amount of money inserted: $1.90

Change:

Quarters: 2

Dimes: 1

Nickels: 1

Pennies: 0

Do you have another entry?: Yes

Enter price of item: $1.25

Enter amount of money inserted: $2.60

Change:

Quarters: 5

Dimes: 1

Nickels: 0

Pennies: 0

Do you have another entry?: Yes

Enter price of item: $2.00

Enter amount of money inserted: $2.00

No Change

Do you have another entry?: Yes

Enter price of item: $1.25

Enter amount of money inserted: $1.00

Error: Not enough money inserted.

Do you have another entry?: No

NOTE: This question has been asked before but it uses some other format. It should be close to this

import javax.swing.JOptionPane;

public class VendingMachine

{

public static void main(String[] args)

{

double Price = Double.parseDouble(JOptionPane.showInputDialog(null, "Enter the price of item: ", "Input", JOptionPane. QUESTION_MESSAGE));

double MoneyDeposited = Double.parseDouble(JOptionPane.showInputDialog(null, "Enter amout of money deposited: ", "Deposite Money", JOptionPane. QUESTION_MESSAGE));

For example:

if(MoneyDeposited

{

JOptionPane.showMessageDialog(null, "Error: Not enough money inserted", "Faiure", JOptionPane.ERROR_MESSAGE);

}

Or this

JOptionPane.showMessageDialog(null, "Message Contents", "Window Title", JOptionPane.PLAIN_MESSAGE);

It shoul not have these kinds of codes: These codes are from the question above

import javax.swing.JDialog;

import javax.swing.JOptionPane;

float itemPrice,moneyInserted

dialog.setAlwaysOnTop(true);

dialog.setVisible(true);

int pennies =Math.round((moneyInserted-itemPrice)*100)
