Chapter 4 Exercise 26, Introduction to Java Programming, Tenth Edition Y. Daniel LiangY.

*4.26 (Financial application: monetary units) Rewrite Listing 2.10, ComputeChange. java, to fix the possible loss of accuracy when converting a float value to an int value. Read the input as a string such as "11.56". Your program should extract the dollar amount before the decimal point and the cents after the decimal amount using the indexOf and substring methods.

import java.util.Scanner;
 
public class ProgrammingEx4_26 {
  public static void main(String[] args) {   
    // Create a Scanner
    Scanner input = new Scanner(System.in);
 
    // Receive the amount 
    System.out.print(
      "Enter an amount in double, for example 11.56: ");
    String amount = input.next();
    int numberOfOneDollars = Integer.parseInt(amount.substring(0, amount.indexOf('.')));
    int numberOfCents = Integer.parseInt(amount.substring( amount.indexOf('.')+1));
 
 
 
    // Find the number of quarters in the remaining amount
    int numberOfQuarters = numberOfCents / 25;
    numberOfCents = numberOfCents % 25;
 
    // Find the number of dimes in the remaining amount
    int numberOfDimes = numberOfCents / 10;
    numberOfCents = numberOfCents % 10;
 
    // Find the number of nickels in the remaining amount
    int numberOfNickels = numberOfCents / 5;
    numberOfCents = numberOfCents % 5;
 
    // Find the number of pennies in the remaining amount
    int numberOfPennies = numberOfCents;
 
    // Display results
    System.out.println("Your amount " + amount + " consists of"); 
    System.out.println("    " + numberOfOneDollars + " dollars");
    System.out.println("    " + numberOfQuarters + " quarters ");
    System.out.println("    " + numberOfDimes + " dimes"); 
    System.out.println("    " + numberOfNickels + " nickels");
    System.out.println("    " + numberOfPennies + " pennies");
