ArrayList Study

Grocery List Application

• To get used to what an ArrayList is and how it operates, I am creating a grocery list application
• Methods that have been created:
  • Add an item
  • Printing out the list
  • Modifying a single item in the grocery list
  • Deleting an item from the grocery list
  • Find an item in the grocery list

Simple Mobile Phone

• Create a program that implements a simple mobile phone, it needs to do the following:
  • Able to store, modify, remove and query contact names
  • Master class called MobilePhone, that holds the ArrayList of Contacts
  • Create a simple class for Contacts (name and phone number)
  • Menu options:
    • Quit
    • Print list of contacts
    • Add New Contact
    • Update existing contact
      • When adding and updating contacts, make sure that the contact exists (use name)
    • Remove contact
    • Search/find contacts
  • ArrayList inner workings should not be exposed to MobilePhone
    • e.g. no ints, no .get(i), etc
  • MobilePhone should do everything with Contact objects only

Banking Application (using Autoboxing and Unboxing)

• Create a simple banking application, it needs to have/do the following:
  • Have a Bank Class
  • It should have an ArrayList of Branches
    • Each Branch should have an ArrayList of Customers
  • Customer class should have an ArrayList of Doubles (transactions)
  • Customer
    • Name, and ArrayList of doubles
  • Branch
    • Need to be able to add new customer and initial transaction amount
    • Also needs to add additional transactions for that customer/branch
  • Bank
    • Add a new Branch
    • Add a new Customer to that Branch with initial transaction
    • Add a transaction for an existing customer for that branch
    • Show a list of Customers for a particular Branch and optionally a list of their transactions
  • Demonstrate Autoboxing and Unboxing in code
    • Hint: Transactions
  • Add data validation
    • Check if exists or does not exist
