The first is a $.$zip file that contains all the source code for the project. The $.$zip file should contain only source code and nothing else, which means only the $.$java files. If you elect to use a package the $.$java files should be in a folder whose name is the package name. Every outer class should be in a separate $.$java file with the same name as the class name. Each file should include a comment block at the top containing your name, the project name, the date, and a short description of the class contained in that file.
