Write a program that prompts the user for a dollar amount. The program outp
uts the fewest number of
coins needed. For example:
Enter total amount: $
1.71
You have 6 quarters, 2 dimes, 0 nickels, and 1 penny.
Note: due to numerical error
2
you must convert the initial input to an integer
the number of pennies
before performing a
ny calculations. Once computed as a double (i.e. 171.0), you have been supplied a
method (
convertToInt
, which you MUST use) to convert the double to an integer (i.e. 171). Only then
proceed to compute number of coins.
Starter code:

| public class LA1c { | |
| /** | |
| * Error message to display for negative amount | |
| */ | |
| public static final String ERR_MSG = "Dollar amount must be non-negative!"; | |
| /** | |
| * Method to convert a double to | |
| * an integer | |
| * | |
| * @param num number to convert | |
| * @return converted value | |
| */ | |
| public static int convertToInt(double num) { | |
| return (int) Math.round(num); | |
| } | |
| // TODO: document this method | |
| public static void main(String[] args) { | |
| // TODO: write your code here | |
