Dollar Change Program Help needed!!

Question

I need some immediate help writing a java program that determines change of 1 dollar recieved in the amout of quarters, dimes, and nickels when an item is purchased between the prices of 25cents and a dollar. For Example:
Total Money: $1 (static)
Enter the price of the item in cents: 45
You bought an item for 45 cent and gave me a dollar, so your change is:
2 quarters,
0 dimes, and
1 nickel.
That is the basics of what I need, and I am not sure where to start.

Answer 1

My program works as long as there is at least 1 penny to be given back in the change. I need help!
//          CoinCounter.java
//          This program counts the change given back from 1 dollar
//          in specific values such as quarters, dimes, and nickels
//          and pennies.

     int changeRequired = dollar - cost;
     while(changeRequired > 0){
          if((changeRequired - quarter>= 0){
          numQuarters ++;
               changeRequired -= quarter;
                    continue;
          if(changeRequired - dime >= 0){
          numDimes ++;
               changeRequired -= dime;
                    continue;
          if(changeRequired - nickel >= 0){
          numNickels ++;
               changeRequired -= nickel;
                    continue;
          if(changeRequired - penny >= 0){
          numPennies ++;
               changeRequired -= penny;
//Amount of change needed to give back
     int change = dollar - cost;
//System print out
     System.out.println("The change required for $1.00 from an item costing "
          + cost + " Cents is " +change+ ". Here is your change:");
          System.out.println(numQuarters+" Quarters");
          System.out.println(numDimes+" Dimes");
          System.out.println(numNickels+" Nickels");
          System.out.println(numPennies+" Pennies");
