Hey can anyone help me with this
Vending Machine
For this purposes of this project, imagine a vending machine that has only one product that costs a fixed price.
For this machine you can put in nickels, dimes, quarters, and dollar bills which increase the balance by .05, .1, .25 and 1.0 respectively.
If enough money is put in, it can dispense the product and return change if needed.
Data Entry:
Money:
B – Bill 1.00
Q – Quarter .25
D – Dime .10
N – Nickel .05
Data Entry:
Commands:
R – Refund – returns “balance”
P – Product – if balance is sufficient, dispenses product, reduces balance by 1.25, and if there is a remaining balance dispenses that too.
– if balance is not sufficient tells user a product can’t be dispensed
X – eXit – terminates program
Explanation / Answer
ProductDispencedMachine.java
import java.util.Scanner;
public class ProductDispencedMachine {
public static void main(String[] args) {
// Declaring variables
char choice;
double balance = 0.0;
Scanner sc = new Scanner(System.in);
// this loop continue to execute until unser enters 'X"
while (true) {
// Displaying menu
System.out.println(" Money:");
System.out.println("B - Bill");
System.out.println("Q - Quarter");
System.out.println("D - Dime");
System.out.println("N - Nickel");
System.out.println("R - Refund");
System.out.println("P - Product");
System.out.println("X - Exit");
// Getting the choice entered by the user.
System.out.print("Enter choice :");
choice = sc.next(".").charAt(0);
// Based on the users choice the corresponding case will get
// executed.
switch (choice) {
case 'B':
case 'b': {
// Adding 1.00 to the current balance
balance = balance + 1.00;
// Displaying the balance after adding money
System.out.printf("Amount :%.2f", balance);
System.out.println(" ");
continue;
}
case 'Q':
case 'q': {
// Adding 0.25 to the current balance
balance = balance + 0.25;
// Displaying the balance after adding money
System.out.printf("Amount :%.2f", balance);
System.out.println(" ");
continue;
}
case 'D':
case 'd': {
// Adding 0.10 to the current balance
balance = balance + 0.10;
// Displaying the balance after adding money
System.out.printf("Amount :%.2f", balance);
System.out.println(" ");
continue;
}
case 'N':
case 'n': {
// Adding 0.05 to the current balance
balance = balance + 0.05;
// Displaying the balance after adding money
System.out.printf("Amount :%.2f", balance);
System.out.println(" ");
continue;
}
case 'R':
case 'r': {
// Returned money
System.out.printf("Returned Amount :%.2f", balance);
System.out.println(" ");
balance = 0;
continue;
}
case 'P':
case 'p': {
if (balance >= 1.25) {
System.out.println("Product Dispensed ");
// Subtracting 1.25 from balance
balance = balance - 1.25;
System.out.printf("Balance Amount Returned :%.2f", balance);
System.out.println(" ");
} else {
// If the amount is less than 1.25 then ,it will display
// Error message
System.out.println("Product can't be dispensed");
}
continue;
}
case 'X':
case 'x':
break;
}
break;
}
}
}
