Let's say, I have the following structure:
I want all classes from first
package to be imported in all classes in my second
package.
Now I'm just specifying for every class in second
package:
import first.*;
Can I import once for all classes in package?
No, it cannot be done.
I don't see why this is such a hardship.
A better solution would be to use an IDE that can add the imports as you need them.
I'd also recommend spelling each one out individually rather than using the star notation, even if you need to import all of them. It documents your intent better, and that IDE can make it transparent to you.
