How do I reset my local branch to be just like the branch on the remote repository?

I did:

git reset --hard HEAD

But when I run a git status,

On branch master
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)
      modified:   java/com/mycompany/TestContacts.java
      modified:   java/com/mycompany/TestParser.java

Can you please tell me why I have these 'modified'? I haven't touched these files? If I did, I want to remove those.
