How do I import specific classes ?

Hi.
Lately I seem to import a lot of classes, and I suspect that it would create a large foot-print e.g.
import java.awt.image.MemoryImageSource;
is in my view better than
import java.awt.image.*;
So how do I find out which specific classes I need ???
I tried the javac -verbose , is that the only way ?

To answer your question. import on demand, importing packageName.*;,
is just as efficient.

I'd reference the jls, but somebody stole my copy [damned people].
Who the fuk steals a jls, anyway?

There is no difference.
import java.awt.*; versus
import java.awt.Button is the same.
When importing you are not 'including' resources in your program. It is just a convenient way to write code so you don't have to specify
the fully qualified path to an object.

Java:
The power, elegance, and simplicity of a hand grenade

I thought that was C++. Or maybe it was perl.

Thanks all
I wish I could buy you people drinks or something for all the free help I have gotten here over the last few months...

After reading this thread, I realized that the reason that I write specific import statements like java.util.LinkedHashMap instead of java.util.*, is for documentation. I can look at the first few lines of code and see the detailed dependencies.
With a relatively small package, such as java.util.regex, it doesn't matter, but for java.util.* or java.sql.* I kind of like to know what parts of the API I'm leveraging. So I will probably continue to import specific classes most of the time.
It is nice to know that there aren't any performance penalties for using the "splat" version though.
Happy importing!
