Assignment

It says that now you will need to convert the use of Array Lists to Linked Lists.I need help changing this part im no sure what to do exactly/ You will also need to maintain order in your systemwhether alphabetical or numerical. Note: take great care when implementing these types of lists, it is very easy to lose track of your various nodes. As for storage, you will need to implement one form of storage (at a minimum) for your data. You will use files to do this. The difference between the files used in CSCI 140 and this course, is the use of objects. You will store and read objects. You do not have to store every piece of data (although this will be a true test of what you know), you may choose one type of data OR if you have one large object, you are storing all of your data.
