I really need help here. This is for a class assignment, yet I'm not getting any help from anyone, anywhere, including my instructor. This is an online class, and he is never available. Since this is for a class, I need to keep things the way they are. Meaning that I need the outside class, and all of the setter/getter methods. This is for a basic address book. I need the Storage class to calculate numdonationAmount*numDonationsYTD. This calculation cannot be within found anywhere in AddressBook.java. It must be found in Storage.java. I have damn near most of it. Also, I can't get the Decimal formatter to work properly. I can't get it to work properly using the printf command, either. I need the output to be the name, address, city, state, zip, how many times this person donated, and the total amount of all donations (donate amount * how many times this person donated). Here is my code. I am on the verge of giving up. I just can't seem to understand java, at least in the way that I am being taught. The first part is AddressBook.java, and the second is a class I created, Storage.java

}The formatted text needs to be in the output in a USD format. Output needs to be like this:
idName lives at idAddress, idCity, idState, idZip, and has donated numDonateAmount times. The total of all donations amount to numDonateTotal.
Now, I need to grab numDonateAmount from Storage class, and numDonateTotal needs to be in dollar format. Please tell me what I'm doing wrong.
