Use JavaWrite a program that will simulate a change machine found at cash registers. Input the amount due and amount paid from t

Ksju [112]

Answer:

Here is the JAVA program:

import java.util.Scanner; //to accept input from user

public class Main { // class name

public static void main(String [] args) { // start of main method

Scanner input = new Scanner(System.in); // creates Scanner class object to take input from user

System.out.println("Please Enter the Cost of the Item: "); // prompts user to enter the cost of item

double itemCost = input.nextDouble(); //scans and reads the input value of item cost

System.out.println("Please Enter the Amount Paid: "); // prompts user to enter the amount paid

double amount = input.nextDouble(); //scans and reads the value of amount from user

int change = (int)(amount * 100 - itemCost * 100); //compute the remaining amount i.e. change

System.out.println("Change Owed: " + change / 100.0); // displays the owed change

int quarters = change / 25; // computes the value for quarters

change = change % 25; // compute the quarters remaining

int dimes = change / 10; // computes dimes

change = change % 10; // computes dimes remaining

int nickels = change / 5; // computes nickels

change = change % 5; // compute nickels remaining

int pennies = change; // computes pennies

System.out.println("Quarters: " + quarters); // displays computed value of quarters

System.out.println("Dimes: " + dimes); // displays value of dimes

System.out.println("Nickels: " + nickels); // displays value of nickels

System.out.println("Pennies: " + pennies); }} //displays value of pennies

Explanation:

I will explain the program with an examples.

Suppose the user enters 4.57 as cost of the item and 5.00 as amount paid. Then the program works as follows:

Change is computed as

change = (int)(amount * 100 - itemCost * 100);

This becomes;

change = (int)(5.00 * 100 - 4.57 * 100)

= 500 - 457

change = 43

Now the change owed is computed as:

change / 100.0 = 43/100.0 = 0.43

Hence change owed = 0.43

Next quarters are computed as:

quarters = change / 25;

This becomes:

quarters = 43/25

quarters = 1

Now the remaining is computed as:

change = change % 25;

This becomes:

change = 43 % 25;

change = 18

Next the dimes are computed from remaining value of change as:

dimes = change / 10;

dimes = 18 / 10

dimes = 1

Now the remaining is computed as:

change = change % 10;

This becomes:

change = 18 % 10

change = 8

Next the nickels are computed from remaining value of change as:

nickels = change / 5;

nickels = 8 / 5

nickels = 1

Now the remaining is computed as:

change = change % 5;

This becomes:

change = 8 % 5

change = 3

At last the pennies are computed as:

pennies = change;

pennies = 3

So the output of the entire program is:

Change Owed: 0.43 Quarters: 1 Dimes: 1 Nickels: 1 Pennies: 3

The screenshot of the output is attached.
