Duke project

This is a chatbot with basic functionality to add, remove, update and delete tasks. It has a basic GUI written with JavaFX. It saves added tasks to a file called duke.txt within the same folder, and loads from this file if it already exists.

Adding a Task

There are three types of Tasks: Todo, Deadline and Event.

To add a Todo: todo <TASKNAME>
Example: todo borrow book adds the task borrow book to Duke.

To add a Deadline: deadline <TASKNAME> /by <DEADLINE>
The format for DEADLINE is YYYY-MM-DD HHMM.
Example: deadline read book /by 2012-12-12 1530 adds a deadline to read book by 12th December 2012, 3:30PM.

To add an Event: event <TASKNAME> /at <STARTDATE> <ENDDATE>
The format for STARTDATE and ENDDATE is both YYYY-MM-DD HHMM.
Example: event house warming /at 2012-12-12 1530 2012-12-12 1700 adds an event for housewarming which takes place from 12th December 2012, 3:30PM to 12th December 2012, 5PM.
