We are going to create a LinkedList of Accounts. Create a Class called AccLinkedList, and store it in a file called AccLinkedList.java. Example Included below. Remember back in Lab #1, you created an Account Class. Pull that class into this lab. Add a next property. Then build an AccLinkedList class that will store Accounts in a LinkedList in Order by Balance. That is the Highest balance should be at the head of the List and the lowest balance should be at the end of the list. Also include a display() method, that displays this linked list. In the main create and add 5 Account objects to your LinkedList, then print out this LinkedList. Make up the data for each account. The LinkedList should be in order by Balance.
