what's difference between the 'git apply' and 'git fetch'?

when I pull patch from gerrit，a question come:
what's difference between the 'git apply' and 'git fetch'?

cp patch /the/path/save
git apply patch

and

git fetch ssh://someone@gerrit.(SOME INFOMATION)  && git cherry-pick FETCH_HEAD

Are they the same thing? or do a first and then b

a,b can‘t be done at the same time.It seems that they do the same thing,but I still cannot understand what difference between them.

Even if fed the same commit contents, the result will differ:

  • git cherry-pick will create a commit that's a copy of the specified commit and retain the original commit information (author, author-date, commit message)
  • git apply will read a diff/patch file and apply it to your current working directory.
    It will not create a commit and if you do commit the resulting changes, the original commit information will not be in that commit.
    (Unless you manually add it yourself)

However, there's also git am -k which you can use to import a patch created by git format-patch -k. Then you should end up with a commit that's a copy of a commit, similar to cherry-picking.
