Question

1. [10 marks] (Changes.java) Write code that asks the user to enter an amount of money from 0 to 99 cents. The program then calculates and displays the number of coins from each denomination: quarters (25 cents), dimes (10 cents), nickels (5 cents), and cents. For example, if the user enters 93, your program should display There are 3 quarters, 1 dimes, 1 nickels, and 3 cents in 93 cents Note: You must use integer division and modular division to find the digits.

import java.util.Scanner;

public class Change{
        public static void main(String[] args) {
                int amount=0,d=0,q=0,n=0,p=0,di=0;
                  System.out.printf("Enter amount: ");
                  Scanner sc = new Scanner(System.in);
                  amount=sc.nextInt();
                  if(amount==0){
                    System.out.printf("no change");
                    return;
                  }
                  //finding dollors
