The Exact change program written in java programming language, where comments explain each action purposes

import java.util.*;

public class Money{

public static void main(String [] args){

Scanner input = new Scanner(System.in);

// Declare Variables

int amount, dollar, quarter, dime, nickel, penny;

// Prompt user for input

System.out.print("Amount: ");

amount = input.nextInt();

// Check if input is less than 1

if(amount<=0)  {

  System.out.print("No Change");  }

else  {

  // Convert amount to various coins

  dollar = amount/100;   amount = amount%100;

  quarter = amount/25;   amount = amount%25;

  dime = amount/10;   amount = amount%10;

  nickel = amount/5;   penny = amount%5;

  // Print results

  if(dollar>=1)    {

    if(dollar == 1) { System.out.print(dollar+" dollar\n");}

  else { System.out.print(dollar+" dollars\n"); }

}

if(quarter>=1){

if(quarter== 1){System.out.print(quarter+" quarter\n");}

else{System.out.print(quarter+" quarters\n");}

}

if(dime>=1){
