How do I write this program using java.io.*

instead of java.util.Scanner????

Develop a Java program that computes which bills and coins will be given as change for a sales transaction. Available bills are: $20 $10 $5 $1 Available coins are: quarter (25 cents) dime (10 cents) nickel (5 cents) penny (1 cent) Only print the actual bills and coins returned. Do not print unused denominations (for example, if no $10 bills are returned, do not print anything regarding $10 bills). Example: What is the total sales charge? 58.12 How much is the customer giving? 100.00 The change is: 2 $20 bills 1 $1 bill 3 quarters 1 dime 3 pennies

Here is the code using java.util.Scanner

mport java.util.Scanner;

public class changeMaker {

/**

*

*/

public static void main(String[] args) {

Scanner keyboard = new Scanner(System.in);

int price;

int provided;

int change;

System.out.print("What is the total sales charge?");

price = (int) Math.round(keyboard.nextDouble() * 100);

System.out.print("How much is the customer giving?");

provided = (int) Math.round(keyboard.nextDouble() * 100);

if (provided > price) {

System.out.println("The change is:");

change = provided - price;

// Since you multiplied by 100 you have to divide by 2000 to get the number of twenties for change.

int twenties = change / 2000;

if (twenties > 0) { //if the change is less than $20 this will be a zero

change = change % 2000; // this resets the value of change to the remainder after the twenties are calculated but only if there was at least enough to make one twenty

System.out.println(twenties + " $20 bill(s)");

}

int tens = change / 1000;

if (tens > 0) {

change = change % 1000;

System.out.println(tens + " $10 bill(s)");

}

int fives = change / 500;

if (fives > 0) {

change = change % 500;

System.out.println(fives + " $5 bill(S)");

}

int ones = change / 100;

if (ones > 0) {

change = change % 100;

System.out.println(ones + " $1 bill(s)");

}

int quarters = change / 25;

if (quarters > 0) {

change = change % 25;

System.out.println(quarters + " quarter coin(s)");

}

int dimes = change / 10;

if (dimes > 0) {

change = change % 10;

System.out.println(dimes + " dime coin(s)");

}

int nickels = change / 5;

if (nickels > 0) {

change = change % 5;

System.out.println(nickels + " nickel coin(s)");

}

int pennies = change;

System.out.println(pennies + " penny coin(s)");

}

if (provided < price) { // this statement is saying that if the customer doesn't pay enough, it will tell the user

System.out.print("Not enough money!");

}

else if (provided == price) {

System.out.print("No change is necessary!");

}

}

}
