Hi 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 1000 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 be the concerns so that it works efficiently on a device where memory is limited?

Thanks!
