Hello,

Please help write program that calculates coins in Java

Program should do the following:

1) Prompts the user to enter a positive integer.

2) The program should calculate the least possible number of coins and display the result.

3) The program MUST display the results using proper grammar (singular or plural).

4) The program MUST validate the user input and NOT allow ANYTHING that is not an integer greater than or equal to zero.

The program’s display must adhere to the following rules:

One “coin” per line.

Proper use of the singular or plural nouns; example 1 dime or 2 dimes.

Only display coins that are actually used in the result.

Acceptable display examples include:

2 quarters

1 dime

3 pennies

UNACCEPTABLE examples include:

2 quarter(s)

1 dime(s)

1 nickel

1 penny

0 dimes

0 nickels

3 pennies

GENERAL RESTRICTIONS

No break statements to exit loops

Thank you

Explanation / Answer

CoinsTest.java

import java.util.Scanner;

public class CoinsTest {

  
   public static void main(String[] args) {
       Scanner scan = new Scanner(System.in);
       System.out.println("Enter a positive integer(-1 to quit): ");
       int amount = scan.nextInt();
      
       while(amount !=-1){
      
       if(amount <=0 ){
           System.out.print("Invalid Input. ");
       }
       else{
           int quarters = amount / 25;
           amount = amount % 25;
           int dimes = amount/ 10;
           amount = amount % 10;
           int nickels = amount / 5;
           amount = amount % 5;
           int penny = amount;
           if(quarters != 0){
           if(quarters == 1)
           System.out.println(quarters+" quarter");
           else
               System.out.println(quarters+" quarters");  
           }
           if(dimes != 0){
               if(dimes == 1)
               System.out.println(dimes+" dime");
               else
                   System.out.println(dimes+" dimes");  
               }

           if(nickels != 0){
               if(nickels == 1)
               System.out.println(nickels+" nickel");
               else
                   System.out.println(nickels+" nickels");  
               }

           if(penny != 0){
               if(penny == 1)
               System.out.println(penny+" penny");
               else
                   System.out.println(penny+" pennies");  
               }

       }
       System.out.println("Enter a positive integer(-1 to quit): ");
       amount = scan.nextInt();
      
   }
      
      
   }
}

Output:
