How to push commit to git repository without adding Remote?

Question

I have some repository, like https://nickname@bitbucket.org/nickname/repo-name.git. I need to push some data to this repo, using Java.

So, basically I want to do these steps:

Create temporary directory (tmp_path == /temp/tmp/dir)
cd tmp_path
git init
git remote add origin https://nickname@bitbucket.org/nickname/repo-name.git
create temp file with needed data (filanme == tmpfile.txt)
git add filename
git commit --message="adding tmp file"
git push origin tmp-branch

But there is one problem. I cannot make "cd" from Java. So I need another solution.

Is there any way to push some data to repository without local git folder?

Do you plan to start new processes to execute these commands? If so, yes, there is a way to start the process from a specific directory: https://docs.oracle.com/javase/8/docs/api/java/lang/ProcessBuilder.html#directory-java.io.File-. But there are Java APIs to use git from Java, without starting processes. It's unclear what you actuallly want to do, since you didn't post any code. — JB Nizet, Sep 29 '18 at 12:07
@JBNizet my final target is to push List of userData to some branch of specific git repo. Thank you for link, I will see it. — Max, Sep 29 '18 at 12:16

I'm not familiar with Java, so I can just give commands without cd.

git init /temp/tmp/dir
# create tmpfile.txt in /temp/tmp/dir
git --git-dir=/temp/tmp/dir/.git --work-tree=/temp/tmp/dir add tmpfile.txt
git --git-dir=/temp/tmp/dir/.git commit --message "adding tmp file"
# your question says without adding remote, so we skip "git remote add"
git --git-dir=/temp/tmp/dir/.git push https://nickname@bitbucket.org/nickname/repo-name.git HEAD:refs/heads/tmp-branch
