Add Increment: Level-0

The iP (and the tP) undergoes changes after each semester. As such, teething issues are a possibility. If you encounter any problem while doing the iP/tP, please post in the forum so that we can take necessary actions.

We discourage you from doing project tasks allocated to future weeks. Reasons: In order to help you gain the ability to apply knowledge or do tasks effortlessly as if you have been doing them for a long timefluency (and also to better simulate real projects), we want the project work to be done at multiple times with time gaps in betweenspaced and spread over a longer period, rather than to be done as a short burst.

Reminder: as per iP grading criteria, some increments need to to be done in each week for you to get full marks.

Please follow instructions carefully. Any deviations can cause our grading scripts to miss your work (and result in you not getting credit for the work).

Deadline:

Note the typical deadline weekly project tasks:

Deadline for weekly tasks

The deadline to complete tasks allocated to the week is the e.g., if your tutorial is on Thursday, the deadline is Wednesday 23.59midnight before your tutorial day, unless stated otherwise. Our grading scripts that detect your work run at midnight and only the work that's done by midnight will be eligible for marks (for cases where the task is graded).

But as there are no tutorials this week, you have until Thu, Aug 20th 2359 to finish this week's iP tasks.

1 Learn about the project

Read the following two sections, if you haven't done so already:

The objectives of the individual project (iP) is to learn/refresh the basics of,

Java
OOP
IDEs
Git and GitHub
Project automation tools
Code quality

All skills you will learn in the iP will be useful in the team project (tP). Furthermore, some of the iP code can be adapted for the tP.
The more you do in the iP and farther you push beyond the minimal expectations, the easier it will be in your tP.

The iP is based on the generic project called Project Duke, the overview of which is given below.

Duke Overview

Project Duke

Duke, the Java Mascot
[credit: Wikipedia]

Project Duke is a educational software project designed to take you through the steps of building a small software incrementally, while applying as many Java and SE techniques as possible along the way.

The project aims to build a product named Duke, a Personal Assistant Chatbot that helps a person to keep track of various things. The name Duke was chosen as a placeholder name, in honor of Duke, the Java Mascot. You may give it any other name and personality you wish.

Here is a sample interaction with Duke:

    ____________________________________________________________
      ____        _        
     |  _ \ _   _| | _____ 
     | | | | | | | |/ / _ \
     | |_| | |_| |   <  __/
     |____/ \__,_|_|\_\___|

     Bye. Hope to see you again soon!
    ____________________________________________________________

The project consists of the following increments:

Levels: A series of features, meant to be added to Duke in the given order, although some can be skipped. These have been named Level 1 to Level 10 to indicate how each makes the product progressively "level up".
Extensions:
- Category A These are internal/feature enhancements meant to help you practice a specific Java or an SE technique.
- Category B These are enhancements related to task tracking.
- Category C These are enhancements, not specifically related to task tracking.
- Category D Each of these adds the ability to track another type of entities.

The iP is to be done over the first half of the semester.

Volatile requirements ahead!: Some requirements will only be released later (or could be changed along the way), to simulate how requirements of a project may not be available at the start or stay the same during the project.
Requirements may differ between students!: Note that some requirements that are to be released later could be different from one student to another.

Total: 20 marks

Implementation [10 marks]: Requirements to get full marks:

Achieve more than 90% of all deliverables by the end.
- Requirements marked as optional or if-applicable are not counted when calculating the percentage of deliverables.
- When a requirement specifies a minimal version of it, simply reaching that minimal version of the requirement is enough for it to be counted for grading -- however, we recommend you to go beyond the minimal; the farther you go, the more practice you will get.
The code quality meets the following conditions:
- Reasonable use of OOP e.g., at least some use of inheritance, code divided into classes in a sensible way
- No blatant violations of the coding standard
- At least some errors are handled using exceptions
- At least half of public methods/classes have javadoc comments
- The code is neat e.g., no chunks of commented out code
- Reasonable use of SLAP e.g., no very-long methods or deeply nested code

Project Management [5 marks]: To get full marks, you should achieve,

Submit some deliverables in at least 4 out of the 6 iP weeks (i.e., week 2 - week 7)
Follow other requirements specified (e.g., how to use Git/Github for each increment, do peer reviews) in at least 4 weeks

Documentation [5 marks]: To get full marks, you should achieve,

The product web site and the user guide is reasonable (i.e., functional, not hard to read, covers all features, no major formatting errors in the published view).

You can monitor your iP progress (as detected by our scripts) in the iP Progress Dashboard page.

2 Set up prerequisites

Ensure you have followed the Preparation sections of the following module tools:

The main language used in this module is Java. You should use Java for all programming activities, the project, and exam answers.

Preparation:

We require you to use Java 11 (the Oracle version or the OpenJDK version) for all module work. It is your duty to ensure the code you write (and executables you produce) are compatible with that version of Java. Any incompatibilities will be considered as bugs.

Tool: Git (for revision control)

You are required to use Git. Other revision control software are not allowed. The recommended GUI client for Git is SourceTree, but you may use any other, or none.

Preparation:

Install Git and a Git GUI client on your computer.
SourceTree comes bundled with Git i.e., if you install SourceTree, you get both Git and a GUI client in one shot. If you are already comfortable using Git command line, you need not install/use a GUI client.

Set Git user.name: We use various tools to analyze your code. For us to be able to identify your commits, we encourage you to set your Git user.name in all computers you use to a sensible string that uniquely identifies you. For example, you can set it to your GitHub username or your full name. If this user name is not set properly or if you use multiple usernames for Git, our grading scripts might miss some of your work.

After installing Git in a computer, you can set the Git username as follows:

Open a command window that can run Git commands (e.g., Git bash window)
Run the command git config --global user.name YOUR_GITHUB_USERNAME (omit the --global flag to limit the setting to the current repo only)
e.g., git config --global user.name JohnDoe

More info about setting Git username is here.

Tool: GitHub (for code hosting)

You are required to use GitHub as the hosting and collaboration platform of your project (i.e., to hold the Code repository, Issue Tracker, etc.).

Preparation:

Create a GitHub account (if you don't have one yet), as explained in the panel below.

Create a personal GitHub account if you don't have one yet.

You are advised to choose a sensible GitHub username as you are likely to use it for years to come in professional contexts e.g., in job applications.
Strongly recommended: Complete your GitHub profile. In particular,
- Specify your full name.
- Upload a profile photo that matches our requirements.
The GitHub profile is useful for the tutors and classmates to identify you. If you are reluctant to share your info in your long-term GitHub account, you can remove those details after the module is over or create a separate GitHub account just for the module.
You are discouraged from changing your GitHub username during the semester/exam/grading period as it can cause our auto-grading scripts to miss your GitHub activities. If you do change your GitHub username during that period, please let us know immediately.

More info: See Appendix E - Using GitHub.

Tool: Intellij IDE

You are recommended to use Intellij IDEA for module-related programming work. While the use of Intellij is not compulsory, note that module materials are optimized for Intellij. Use other IDEs at your own risk.

Preparation:

Install the IDE in your computer. You may use the Intellij community edition (free) or the ultimate edition (free for students).
If you have an older version of the IDE, we recommend updating to the latest version.

3 Set up the project in your computer

Read through this week's topics before starting the project.

Fork https://github.com/nus-cs2113-AY2021S1/ip.
Enable the issue tracker of your fork (Go to Settings of your fork, scroll to the Features section, and tick the Issues checkbox). Reason: at times we post feedback on your issue tracker.
If the issue tracker is enabled, you should be able to visit the following URL https://github.com/{your_user_name}/ip/issues e.g., https://github.com/johnDoe/ip/issues
Clone the fork onto your computer.
Set up the project in your IDE as explained in the README file.

4 Add Increment: `Level-0`

From this point onward, commit code at important points. Minimally, commit after completing each increment.

Duke Level-0: Greet

Level 0. Greet

Implement an initial skeletal version of the Duke that simply greets the user and exits.
Example:

____________________________________________________________
 Hello! I'm Duke
 What can I do for you?
____________________________________________________________
 Bye. Hope to see you again soon!
____________________________________________________________

The indentation and horizontal lines are optional.
