My question is not so much a problem as a curiosity. I was under the impression that the * would load everything in a package. For example when I use java sound I use

import javax.sound.*;

however when I did this today it still required me to import each part of the sound package that i wanted to use

import javax.sound.midi.MidiEvent;

import javax.sound.midi.MidiSystem;

import javax.sound.midi.Sequence;

import javax.sound.midi.Sequencer;

import javax.sound.midi.ShortMessage;

import javax.sound.midi.Track;

It doesn't matter two much sense eclipse will auto add most of the imports but in a real app this is going to leave me with a LONG list of imports. The book I am reading told me to use the * and just have the one import and that seems the best method to me. Is there a reason why just using the first example up there will not compile?

The wildcard only makes the classes in the single package visible, not any of the subpackages, there would be possible problems with recursive symbol lookup by the compiler

import javax.sound.midi.*

Thanks Nullw0rm. That makes sense. Now that i look back at the book it told me to do it like you did it. I was trying not to look to much at the example when i wrote the code and i did not understand about the sub packages. +rep
