Import declaration

[rpm27]

Hey, I have a small style question. Which import style is preferable (or better) to use. A single one like

import java.util.System;

or an import-on-demand like

import java.util.*;

? Is there any advantage or disadvantage for each declaration? Thank you.

They are the same... the JVM have it's built in code optimizer.... it removes unnecessary codes/excess codes....

But for me, it is nice to show the specific import.... so that, when i have a problem/ forgot how to implement like this, i can scan easily my previous programs/codes for review.....

for example, i forgot on how to use FileNameExtensi onFilter...
so i could just view my previous codes who has an import with the FileNameExtensi onFilter....

i have subreasons.... yet nonsense... :)

So, depends on you....

Yes, right after writing this post, I convinced myself that import individual classes would help me as I'm a Java beginner. Thanks anyway. :-)

You could even write code without using the import statement as well.
The import statement just saves you a lot of typing.
