Where do you add new methods?

Question

When you add a new method to a class where do you put it? At the end of the class...the top? Do you organize methods into specific groupings? Sorted alphabetically?

Just looking for general practices in keeping class methods organized.

Update When grouped where do you add the new method in the group? Just tack on the end or do you use some sort of sub-grouping, sorting?

Update 2 Mmmm...guess the question isn't as clear as I thought. I'm not really looking for class organization. I'm specifically interested in adding a new method to an existing class. For example:

public class Attendant
{
    public void GetDrinks(){}
    public void WelcomeGuests(){}
    public void PickUpTrask(){}
    public void StrapIn(){}
}

Now we're going to add a new method PrepareForCrash(). Where does it go? At the top of the list, bottom, alphabetically or near the StrapIn() method since it's related.

Answer 1

Near "StrapIn" because it's related. That way if you refactor later, all related code is nearby.

Most code editors allow you to browse method names alphabetically in another pane, so organizing your code functionally makes sense within the actual code itself. Group functional methods together, makes life easier when navigating through the class.

Answer 2

For goodness sake, not alphabetically!

I tend to group my functions in the order I expect them to be called during the life of the object, so that a top to bottom read of the header file tends to explain the operation of the class.
