Duke Task Manager

This is a simple task manager program that allows users to add, mark, unmark, delete and save tasks. These tasks are of three types: todo, deadline and event. These tasks are stored in a file, where users can access this list of tasks at any time.

Setting up in Intellij

Prerequisites: JDK 11, update Intellij to the most recent version.

File Storage System

Duke stores the list of tasks in a file called duke_list.txt in the src directory. The program will create the file if it does not already exist. When the program exits, it will save the current list of tasks to the file. If the file already exists, the program will read the list of tasks from the file when it starts up.
