In the listing 7-1 code the database open() function returns a MyDBAdapter. I couldn't figure out why this function didn't return void, but then in the section "Saving Your To-Do List" item number 6 this function is defined as

Code:

 public void open ()

. Which method is preferable, or in what scenarios should you use each one? Thanks for any clarification.

My guess is that in Listing 7-1, the open() method return the object to enable you to do things like db.open().someOtherMethod(). Either way you want to do it should be fine.
