This project implements an address book library.

An address book contains several Contacts, which is a library we also implement in this assignment.

I use gradle to import dependencies which we need to use in the library.

For every public API exposed, we have a unit test. TestAddressBook is unit test for AddressBook library, and TestContact is a unit test for Contact library.

There's also a Main class as a simple test simulating normal calls for adressbook API. It simply add, remove, sort and do other operations to contacts in address book. There are results showing in System.out for you to check the correctness.

Firstly, make sure you are under directory 'course.assignment'. Then, you could simply run:

./gradlew run

To run the unit tests, simply run:

./gradlew test
