k u don't need to use the import keyword unless ur code is in a package.
now after u compile all ur code. u'll get the respective classes.
so if these classes compose ur library. and u wish to use them in code els where. all u need to do is copy those .class files into the same directory of ur current project. then simply compile ur code like this:
javac -cp . MyTestfile.java
note, u don't really need add any extra lines into ur code to use those classes. its all automaticly taken care of.

also it might sometimes make it easier to package a library of classes into a .jar archive.
and at times if it is soo frequently used u can also drop that .jar (or .class files) into the ext dir in ur java root directory.

it is really easy. all u need to do is add the line package name_of_package; at the top of each file to denote that those classes defined in those .java files to be in that perticular package.
next u compile these files
then u move the respective .class files into a new directory that has the same name as that of the package.
now go and download the jarmaker utility i created (somewhere in the java submissions).
now create a blank file with the word "manifest" in it's name.
drag both the directory and that file onto the jarmaker, it should generate a .jar file.

also note: compiling against a jar archive has a slightly different syntax:
