• Objective - To implement a PhoneBook class which maps a name to many phoneNumber
• Purpose - To establish familiarity Map

Getting Started

• Fork and clone this repository to complete your lab.
• This has been done.

Instructions:

Building a SimplePhoneBook class

• Create a simplePhoneBook class that holds a single phone-number per single name

• You can use an associative data type (one which stores items as keys paired with values).

• Your PhoneBook class should have the following method

  • void add(String name, String phoneNumber)
    • adds an entry to the composite associate data type
  • void remove(String name)
    • removes an entry to the composite associate data type
  • Boolean hasEntry(String name)
    • removes an entry to the composite associate data type
  • String lookup(String name)
    • returns a phone number for the respective input name
  • String reverseLookup(String phoneNumber)
    • returns a name for the respective input phoneNumber
  • List<String> getAllContactNames()
    • returns a list of all names in this PhoneBook

Building a AdvancedPhoneBook class

• Create a PhoneBook class that holds names and phone numbers.

• You can use an associative data type (one which stores items as keys paired with values).

• Your PhoneBook class should have the following method

  • void add(String name, String phoneNumber)
    • adds an entry to the composite associate data type
  • void addAll(String name, String... phoneNumbers)
    • adds many phone numbers to a single name entry
  • void remove(String name)
    • removes an entry to the composite associate data type
  • Boolean hasEntry(String name)
    • removes an entry to the composite associate data type
  • List<String> lookup(String name)
    • returns a phone number for the respective input name
  • String reverseLookup(String phoneNumber)
    • returns a name for the respective input phoneNumber
  • List<String> getAllContactNames()
    • returns a list of all names in this PhoneBook
