Is there any difference in package importing?

[saikrishna cinux]

I have one simple doubt regarding performance
import java.util.Date;
import java.util.*;
I use Date class in my program so i generally use this java.util.*;
to import the class.
but in most of the programs who has developed in my company use this
java.util.Date;
I think by using the above one we can improve the performance by reducing the extra overhead.. by importing all the classes


am i right??

There is absolutely no difference in the performance during runtime. There might be a very very small difference during compilation time, but that difference is ofcourse - very very small

The same topic is discussed here too and a good explanation is available
