Need Java help ASAP : (

[kris1976]

Modify the Inventory Program so the application can handle multiple items. Use an array to store the items. The output should display the information one product at a time, including the item number, the name of the product, the number of units in stock, the price of each unit, and the value of the inventory of that product. In addition, the output should display the value of the entire inventory.
Create a method to calculate the value of the entire inventory.
Create another method to sort the array items by the name of the product.
Post as an attachment in java format.
I am getting error that identifier is needed at lines 87 and 90, I marked them in red... also not sure if the Class inventory is correct so it will sort... please help!! Thanks so much!!

Moved to correct forum.

CD[] = new CD[100];

You haven't given a name to the array.

Change to:

CD[] arOCD = new CD[100];

The term between CD[] and = is the name of the array. That is why you forgot.

thank you so much, but now it is telling me identifier is expected on line 91 which I highlighted in red. ??? I'm not sure how to fix that.. any help would be greatly appreciated.

public void addToInventory(CD)

In the parenthesize you have to give a name to the parameter.

public void addToInventory(CD cd1) {

}

When you declare a variable you have to give it a type and a name.

[kris1976]

Wow that worked, thank you again! Only problem now is that it didn't add in the new CD (Poison) and it didn't display the total Inventory for all the CD's (but there are no errors)?? I really appreciate your help, I have 3 more weeks of this class and it has become so difficult.

Your addToInventory method doesn't do anything. Also you aren't actually creating an Inventory object and galling getInventoryValue.

You need to make an inventory object and code the addToInventory method to add them to the array.
