A to-do list application

Propose

• Keep track of things to do
• Cross things off
• Different views all items, or just completed items, or only outstanding items

User Stories

• As a user, I want to be able to add a task to my to-do list
• As a user, I want to be able to view the list of tasks on my to-do list
• As a user, I want to be able to mark a task as complete on my to-do list
• As a user, I want to be able to delete a task from my to-do-list
• As a user, I want to be able to save the state of the application
• As a user, I want to be able to reload that state from file and resume exactly where they left off at some earlier time

Phase 4: Task 2

In ToDoList class and deleteTask method that has a robust design.

Phase 4: Task 3

I think if I have more time, I want JsonReader and JsonWriter to connect ToDoList rather than ListDemo. I think other parts of UML looks good.
