bypassing the classpath

Hey guys, I have written a myUtilities.java program to make things easyer when I write other programs. The problem I am having is when I use it in other programs and go to compile the other programs I end up having to type in 10 or so different classpaths to get it to compile properly. Is there something I can do to the myUtilities.java program that will make it so that I don't have to type in 10 classpaths when compileing the other programs. I have heard of packages, but I don't know much about them and if they will help or not in my case. Thanks in advance-Dan

Hi Dan,

Packages are ways of logicaly grouping your source files and should be used for all applications which you write.

For writing your own reusable classes this is important - by writing your classes in a package (say myPackage), compiling them and puting the compiled files on your classpath, you can reuse your classes with:

import myPackage.*; // * imports all files in the package myPackage

Do a quick search on google for a java package tutorial and you will soon be up to speed.

Regards,

Jon
