Quick Help
import java.util.Scanner;
public class question7 {
public static void main(String[] args) {
Scanner console = new Scanner(System.in);
System.out.println("Enter price of item");
System.out.print("(from 25 cents to a dollar, in 5-cent increments): ");
int cost = console.nextInt();
int change = 100 - cost;
}
}
This runs for me and asks me to enter price, but when i enter it nothing happens because I have yet to program it in. I was wondering if someone can help me write the code so when i enter a price it outputs the change like so
Enter Price:35 Cents
Your Change is 2 quarters, One Dime, One nickel.
Not just saying the Change is 65 cents. Any help?

Help with your homework; yes! Doing your homework; probably not.
Im not asking you to do it, I have this written already, but I am unsure of how to finish it. Its more than half done i just dont know how to do the last step.
> Your Change is 2 quarters, One Dime, One nickel.
You're going to want the print statement to look like System.out.println("your change is "+quarters+" quarters, "+dimes+" dimes, "+nickels+" nickels, and "+dimes+" dimes.");
So you're going to need int variables for each of those.
Then you need a loop to increment the "quarters" variable and decrement the "un-converted change amount" variable for as long as the "un-converted change amount" is over 25, and a similar loop for nickels and dimes.
That should be functional.

Just think of how you would do it mentally and write in down on a piece of paper. Okay, let's start:
1. The price is 35 cents and someone pays a dollar. The change is 65 cents.
2. Lets say you have counts for
number of quarters = 0
number of dimes = 0
number of nickels = 0
initially.
3. 65 is greater than 25 (quarter), so you can pay a quarter in the change, hence
number of quarters = 1
number of dimes = 0
number of nickels = 0
and the balance remaining = 65 - 25 = 40
4. Again you can take another quarter out since 40 is greater than 25 (quarter), so add a quarter to the change
number of quarters = 2
number of dimes = 0
number of nickels = 0
and the balance remaining = 40 - 25 = 15
5. Now, 15 is less than [and not equals either] 25 (quarter), hence you cannot pay any more quarters. So move onto dimes. Since 15 is greater than 10 (dime), add a dime to the change
number of quarters = 2
number of dimes = 1
number of nickels = 0
and the balance remaining = 15 - 10 = 5
6. Finally, you cannot pay out in dimes because 5 is less than 10 (dime). But 5 equals a nickel. So add a nickel and zero the balance due.
number of quarters = 2
number of dimes = 1
number of nickels = 1
and the balance remaining = 5 - 5 = 0
Problem solved!
Now all you have to do is implement this logic in Java. :p
Thank you both very much, thats all I needed! Unlike the character that had to tell me i needed you to do it for me> Help with your homework; yes! Doing your homework;> probably not.

I am likely to tell you the same if you don't mention that you are looking for the logic rather than the code.
