CS2113/T Website - Admin: iP: Week 3

Do any leftover iP tasks from the previous week
Add Increments (+ commit, tag, push): Level-1, Level-2, Level-3, A-CodingStandard

1 Do any leftover iP tasks from the previous week

Remember to do any leftover increments from the past weeks before starting on the current week's increments. This guideline applies to future weeks too.

2 Add Increments (+ commit, tag, push): `Level-1`, `Level-2`, `Level-3`, `A-CodingStandard`

Implement the following in this context, an increment is a Duke level or a Duke extensionincrements in the given order.

From this point onward, after completing each increment,
- git tag the commit with the exact increment ID e.g., Level-2, A-TextUiTesting
- git push the code to your fork ( git doesn't push tags unless you specifically ask it to)

Level-1: Greet, Echo, Exit

Level 1. Greet, Echo, Exit

Implement a skeletal version of Duke that starts by greeting the user, simply echos commands entered by the user, and exits when the user types bye.
Example:

    ____________________________________________________________
     Hello! I'm Duke
     What can I do for you?
    ____________________________________________________________

list
    ____________________________________________________________
     list
    ____________________________________________________________

blah
    ____________________________________________________________
     blah
    ____________________________________________________________

bye
    ____________________________________________________________
     Bye. Hope to see you again soon!
    ____________________________________________________________

The indentation and horizontal lines are optional.

You are strongly encouraged to customize the chatbot name, command/display formats, and even the personality of the chatbot to make your chatbot unique.

Level-2: Add, List

Level 2. Add, List

Add the ability to store whatever text entered by the user and display them back to the user when requested.

Example:

    ____________________________________________________________
     Hello! I'm Duke
     What can I do for you?
    ____________________________________________________________

read book
    ____________________________________________________________
     added: read book
    ____________________________________________________________

return book
    ____________________________________________________________
     added: return book
    ____________________________________________________________

list
    ____________________________________________________________
     1. read book
     2. return book
    ____________________________________________________________
bye
    ____________________________________________________________
     Bye. Hope to see you again soon!
    ____________________________________________________________

There is no need to save the data to the hard disk.
Assume there will be no more than 100 tasks. If you wish, you may use a fixed size array (e.g., String[100]) to store the items.

Level-3: Mark as Done

Level 3. Mark as Done

Add the ability to mark tasks as done.

list
    ____________________________________________________________
     Here are the tasks in your list:
     1.[✓] read book
     2.[✗] return book
     3.[✗] buy bread
    ____________________________________________________________

done 2
    ____________________________________________________________
     Nice! I've marked this task as done: 
       [✓] return book
    ____________________________________________________________

When implementing this feature, you are also recommended to implement the following extension:

A-Classes

↳ Use a class to represent tasks

While it is possible to represent a task list as a multi-dimensional array containing String, int, boolean etc.primitive values, the more natural approach is to use a Task class to represent tasks.

public class Task {
    protected String description;
    protected boolean isDone;

    public Task(String description) {
        this.description = description;
        this.isDone = false;
    }

    public String getStatusIcon() {
        return (isDone ? "\u2713" : "\u2718"); //return tick or X symbols
    }

    //...
}

Task t = new Taks("read book");
t.markAsDone()

A-CodingStandard: Follow the Coding Standard

A-CodingStandard

↳ Tweak the code to comply with a coding standard

Tweak the code to comply with a chosen coding standard. From this point onward, ensure any new code added are compliant with the coding standard.
