Java application design question
- by ring bearer
I have a hobby project, which is basically to maintain 'todo' tasks in the way I like.
One task can be described as:
public class TodoItem {
private String subject;
private Date dueBy;
private Date startBy;
private Priority priority;
private String category;
private Status status;
private String notes;
}
As you can imagine I would have 1000s of todo items at a given time.
What is the best strategy to store a
todo item? (currently on an XML file)
such that all the items are loaded
quickly up on app start up(the
application shows kind of a dashboard
of all the items at start up)?
What is the best way to design its
back-end so that it can be ported to
Android/or a J2ME based phone?
Currently this is done using Java
Swing. What should I concentrate on so
that it works efficiently on a device
where memory is limited?
The application throws open a form
to enter new todo task. For now, I
would like to save the newly added
task to my-todos.xml once the user
presses "save" button. What are the
common ways to append such a change
to an existing XML file?(note that I don't want to read the whole file again and then persist)
