    Java Code:
    CDInventoryProgram.java:265: class Inventory is public, should be declared in a
    file named Inventory.java
    public class Inventory
    ^
    Looks like the file name is "CDInventoryProgram". You may have only one outer class in the file with the public modifier and this class must have the same name as the file name and will also be the class with the main method. So if the file name is really "CDInventoryProgram" then either change the file name to "Inventory" or remove the public modifier from the Inventory class signature and remove the main method from it.

    Thank you for you response that was exactly the problem. I needed to make the public class name the same as my file name...thank you for your time.
