如何将某些文件推送到Git中的原始服务器/主服务器?

我对Git有点陌生.我想将一些文件推送到我的Git来源(远程).

I am little bit new to Git. I would like to push some files to my Git origin (remote).

我做了什么:

我有我的主人，我创建了一个分支来做一些工作.之后，我将分支合并到了我的主人.在我的工作期间，许多二进制文件和项目文件在本地进行了更改/添加.我希望仅 添加已更改为远程服务器的 .java 文件.

I had my master, and I created a branch to do some job. After that I merged my branch to my master. During my work, a lot of binary files and project files were changed/added locally. I would like only to add .java files which changed to remote server.

(我相信我在自己的分支机构工作时曾尝试过 commits ，只是为了检查其工作原理.)

(I believe that I experimented with commits when I worked on my branch, just to check how it work.)

我的主人对我的起源是最新的(这是我做git pull时得到的.我也做了git fetch origin. 我总是收到(当我运行git status时):

My master is up to date with my origin (that is what I get when I do git pull. Also I did git fetch origin. I always received (when I ran git status):

On branch master Your branch is ahead of origin/master by 12 commits.
  (use "git push" to publish your local commits)

nothing to commit, working directory clean`

我试图添加，提交这些文件，但是运行git status并没有改变.我尝试在新分支上进行添加，提交:

I tried to add, commit those files, but running git status wasn't changed. I tried to do add, commit on the new branch:

On branch NewBranch nothing to commit, working directory clean

我试图重置Head.在Git教程或Stack Overflow中找不到我的问题的解决方案.

I tried to reset Head. I didn't find a solution for my problem in the Git tutorial or on Stack Overflow.

我当然可以将所有文件推送到远程源，但是我认为这不是一个好的解决方案.

Of course I can push all files to remote origin, but I don't think it's a good solution.

我发现了一些重复的问题: 如何推送单个文件，如何将更改仅推送到和如何仅提交某些文件?

Some duplicate questions that I found: How to push a single file, how to push changes made to only certain files?, and How to commit only some files?.
