Compute Denominations

Question

I'm writing a Java program that computes the number of money denominations. I need to display the non-zero denominations only and display singular words for single units like 1 dollar and 1 penny, and display plural words for more than one unit like 2 dollars and 3 pennies. If a zero or a negative amount is entered, it will display a message stating that the amount entered was zero or negative.
I'm having issues with showig the non-zero denominations & singular words, Help anyone?
Here's what I have so far:
// Assignment 3.1: ComputeChange.java
// This program breaks down an currency amount into smaller units
import javax.swing.JOptionPane;
public class ComputeChange
     // main method begins execution of Java program
     public static void main(String[] args)
          double amount; // Amount entered from the keyboard
          // Receive the amount entered from the keyboard
          String amountString = JOptionPane.showInputDialog(null,
               "Enter an amount in double, for example 23.97",
               "Compute Change Input", JOptionPane.QUESTION_MESSAGE);
          // Convert string to double
          amount = Double.parseDouble(amountString);
          int remainingAmount = (int)(amount * 100);
          // Find the number of one dollars
          int numOfOneDollars = remainingAmount / 100;
          remainingAmount = remainingAmount % 100;
          // Find the number of quarters in the remaining amount
          int numOfQuarters = remainingAmount / 25;
          remainingAmount = remainingAmount % 25;
          // Find the number of dimes in the remaining amount
          int numOfDimes = remainingAmount / 10;
          remainingAmount = remainingAmount % 10;
          // Find the number of nickels in the remaining amount
          int numOfNickels = remainingAmount / 5;
          remainingAmount = remainingAmount % 5;
          // Find the number of pennies in the remaining amount
          int numOfPennies = remainingAmount;
          // Display results
          if ( amount == 0 )
               String output = "Your amount is zero";
             JOptionPane.showMessageDialog(null, output,
                  "Currency Breakdown Output", JOptionPane.INFORMATION_MESSAGE);
          else if ( amount < 0 )
               String output = "Your amount is negative";
             JOptionPane.showMessageDialog(null, output,
                  "Currency Breakdown Output", JOptionPane.INFORMATION_MESSAGE);
          else if ( amount > 0 )
               String output = "Your amount " + amount + " consists of \n" +
                    numOfOneDollars + " dollars\n" +
                    numOfQuarters + " quarters\n" +
                    numOfDimes + " dimes\n" +
                    numOfNickels + " nickel\n" +
                    numOfPennies + " pennies";
               JOptionPane.showMessageDialog(null, output,
                    "Currency Breakdown Output", JOptionPane.INFORMATION_MESSAGE);
          System.exit(0);
     } //end main method
}
