performance tuning using select and join

[Naresh Chaurasia]

I was reading about the performance tuning in hibernate and came across the following statment.

select: Lazily load the referenced object or collection with a separate SQL SELECT statement. It is the default value
join: Eagerly load the referenced object or collection using an outer join

I know that in case of hibernte3, the lazy is true by default. That means that the associcated object would be fetched only when its method is called.

Now i wanted to understand that the above statements for select and join holds true only when the lazy is set to false? Please explain.
