AddressBook Level 4 - User Guide

By: Team SE-EDU Since: Jun 2016 Licence: MIT

1. Introduction

AddressBook Level 4 (AB4) is for those who prefer to use a desktop app for managing contacts. More importantly, AB4 is optimized for those who prefer to work with a Command Line Interface (CLI) while still having the benefits of a Graphical User Interface (GUI). If you can type fast, AB4 can get your contact management tasks done faster than traditional GUI apps. Interested? Jump to the Section 2, “Quick Start” to get started. Enjoy!

2. Quick Start

  1. Ensure you have Java version 9 or later installed in your Computer.

  2. Download the latest addressbook.jar here.

  3. Copy the file to the folder you want to use as the home folder for your Address Book.

  4. Double-click the file to start the app. The GUI should appear in a few seconds.

  5. Type the command in the command box and press Enter to execute it.
    e.g. typing help and pressing Enter will open the help window.
