Question

Hello I am currently working with Java. I have a problem that I need to create a program for that goes like this :

Homework Project 3: Write an application that prompts for and reads a double value representing a monetary amount. Then determine the least number of each bill and coin needed to represent that amount, starting with the highest (assume that a twenty-dollar bill is the maximum size needed). For example, if the value entered is 47.63 (forty-seven dollars and sixty-three cents), then the output from the program should print the equivalent amount as

$ 47.63 is equivalent to :
2 twenty dollar bills
0 ten dollar bills
1 five dollar bills
2 one dollar bills
2 quarters
1 dimes
0 nickels
3 pennies

I cannot use anything I have not learned yet. I have only learned simple math operaters, currencyinstance, scanner input, and the different types. I cannot use if statements or loops and I am supposed to use a double value. My question is more of a statement I truly do not know where to begin.

thank you in advance.

Explanation / Answer

import java.util.Scanner;

public class App {
  
   public static void main(String[] args) {
      
       Scanner sc = new Scanner(System.in);
      
       System.out.println("Enter amount : ");
       double val=sc.nextDouble(); // reading double value
   String[] s=String.valueOf(val).split("\."); // splitting around '.'
       // lets for example amount = 47.63
  
       int integeral = Integer.parseInt(s[0]); // getting integeral part, 47
       int fraction = Integer.parseInt(s[1]); // getting fractional part 63
      
       // getting number of twenty dollar bills
       int num_20 = integeral/20;
       integeral = integeral%20; // getting rest amount
       System.out.println(num_20 +" twenty dollar bills");
       //getting number of ten dollor bills
       int num_10 = integeral/10;
       integeral = integeral%10;
       System.out.println(num_10 +" ten dollar bills");
       //getting number of 5 dollor bills
       int num_5 = integeral/5;
       integeral = integeral%5;
       System.out.println(num_5 +" five dollar bills");
       //getting number of 1 dollor bills
       int num_1 = integeral;
       System.out.println(integeral +" 1 dollar bills");
      
       // doing operation with fraction part
      
       int quarter = fraction/25; // 4 quarter= 1 dollar
       fraction = fraction%25;
       System.out.println(quarter+" quarters");
       int nickel = fraction/20;
       fraction = fraction%20;
       System.out.println(nickel+" nickels");
       int dimes = fraction/10;
       fraction = fraction%10;
       System.out.println(dimes+" dimes");
       int pennies = fraction;
       System.out.println(pennies+" pennies");

   }
}

/*

OUTPUT:

Enter amount :
47.63
2 twenty dollar bills
0 ten dollar bills
1 five dollar bills
2 1 dollar bills
2 quarters
0 nickels
1 dimes
3 pennies
