Java program calculate change cashier 

Calculating change can be a tricky task for cashiers, especially when dealing with large amounts of money. However, with the help of a simple Java program, this task can be made much easier. In this blog post, we will be discussing how to create a Java program that can calculate the change that a cashier should give to a customer.

Here is the code for the program:

import java.util.Scanner;

public class ChangeCalculator {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        
        System.out.print("Enter the total cost of the purchase: ");
        double totalCost = scanner.nextDouble();
        
        System.out.print("Enter the amount paid by the customer: ");
        double amountPaid = scanner.nextDouble();
        
        double change = amountPaid - totalCost;
        
        System.out.println("The change is: $" + change);
    }
}

The program begins by importing the Scanner class, which is used to read input from the user. Next, we create a new instance of the Scanner class and use it to read the total cost of the purchase and the amount paid by the customer. The program then calculates the change by subtracting the total cost from the amount paid. Finally, the program prints the change to the console.

The above code is a basic program to calculate the change and display it. You can add more functionality like converting the change amount to the number of notes and coins.

In conclusion, with the help of a simple Java program, calculating change for cashiers can be made much easier. The code provided in this blog post can be used as a starting point for creating a more advanced program that can handle more complex calculations.
