How to add automatically the imports in a Java project?

I generate (from a progam java) some Java classes but actually, I don't add the import in each class. I'd like to have a kind of parser that is able to see which import needs to be added in a class. Maybe, it's possible to reuse the fonctionnality of Eclipse because it's able to do that. However, I don't know where I can find that.

Do you have any idea?

Many thanks,

Bat

What about using only Full Qualified Names for classes when creating the code for the generated Java classes?

I see now... the problem is definitely on your generator. Work on that because even if you can extract the functionality from Eclipse, you won't get a 100% working solution every time. So my suggestion is just forget it and fix your generator.

As Paul said, you have to decide the imported class yourself. I usually type on Eclipse and at the end of the class I press Ctrl+Space to get some suggestions. So, for example I want to have java.util.Date, I will write Date and then Ctrl+Space and select java.util.Date and Eclipse will automatically import java.util.Date for me.

If the code is already there, I will do quick fix (F1 on Eclipse) and it will also suggest some fixes to the code I have (one of them is to import the suitable class).

What are you going to do about name collisions? You use a "Date" - is it java.util.Date or java.sql.Date? You use a "XMLFoo", is it com.foomatics.XMLFoo or is it org.openfoo.XMLFoo? It's better to add the imports as you add the code.

Maybe you can create a HashSet of all the imports you're going to need as you generate the code, and then add them in at the top when you're done?
