Java To-Do List

This program is a simple command-line to-do list application in Java that allows the user to manipulate the list and its items.

Input a task to append it to the list. You can also input slash-commands.

Commands :

• /add {task} : appends the task to the list
• /insert {index} {task} : inserts the task to the given index
• /del {index} : deletes the task at the given index
• /edit {index} {task} : replace the task's text at the given index with the new given text
• /done {index} : marks or unmarks the task at the given index as done
• /! {index} : marks or unmarks the task at the given index as important
• /clear : clears the entire list
• /save {listname} : saves the current list of task with their properties to a list of the given name ; each time you change the current list, changes will be saved ; the default list at program launch is todo
• /load {listname} : opens the list with the specified name, and sets it as the current list
• /help : prints help, with instructions and commands

Note : indexes in commands start from 1.

You can also directly open a list by passing its name as an argument at launch. List names cannot contain underscores _ ; hyphens - will be used instead.
