Interface UML

You need to organize your source files

https://github.com/Hodge-zf/lightbulb/tree/master/edu/jalc/lightbulb

Proper parts need to be in proper directories. As you scale your project (lab 4), you will hate life with them all in one spot.

.class files should not be committed

in the root of your repository directory, create a .gitignore file. Make sure to add the preceding ..

In that file add *.class

git add .
git commit -am 'adds ignore file'

Now delete all your *.class files. You can do this from the command line as rm *.class from the class files are located. If you move stuff around, you will need to follow them.

now do git add . again. This will "add" the removed files. Counter-intuitive, I know.
then git commit -am 'removes .class files'
then git push.
