    int dollars = amount / 100;
    //number of dollars
    int dollarValue = dollars % 100;
        // value of quarters 
    int amount; 
    amount = dollarsValue;
 
 
    int quarters = amount / 25; 
        //number of quarters
    int quartersValue = quarters % 25; 
        //value of quarters
    amount -= quartersValue;
 
 
    int dimes = amount / 10; 
        //number of dimes
    int dimesValue = dimes % 10; 
        // The value of the dimes
    amount -= dimesValue;
 
 
    int nickels = amount / 5; 
        //number of nickels
    int nickelsValue = nickels % 5; 
        //value of nickels
    amount -= nickelsValue;
 
    int pennies = amount/ 1; 
        //number of pennies
    int penniesValue = pennies % 1;
        //value of pennies
    amount -= penniesValue;
 
 
 
 
System.out.println ("Dollars: " + dollars);
System.out.println ("Quarters: " + quarters);
System.out.println ("Dimes: " + dimes);
System.out.println ("Nickels: " + nickels);
System.out.println ("Pennies: " + pennies);

Your logic w.r.t. dollars, quarters, dimes etc. seems correct; you forgot to read
the 'amount' variable which is crucial here. Have a look at the Scanner class.

Exactly as I wrote: you prompt the user to enter a number but there is no code
whatsoever that actually reads a number; I suggested to use a Scanner class
for the reading.

I've changed your thread title to something more specific to your problem. Please remember that next time.
Also use code tags everytime when posting code in the forums.

It's okay. Whenever someone says: look at [insert name here] class, they mean refer to Java's API. Remember, Java.sun.com is your best Java friend.

Here you will find this link:

Scanner Class

Scanner class allows you to take input from the user. I would suggest reading the documentation presented in this document because I can't explain it as well as Sun can.

Furthermore, I think there is something funky going on with your brakets. Are you sure it does anything? or even compiles?
