Git only kept my java files and deleted the rest

Question

It was my first time using git and I wanted to add a project to github, I used the following commands:

git init
git add .
git commit -m "Commit 1"
git remote add origin <my url>
git push origin master

As soon as I did this I noticed git deleted all my local files that were in that folder and the only files I got in my repository were java files, so all the rest was deleted.

Any way to revert back the damage?
