When files are being modified in Emacs, a temporary file is created in the working directory that looks like this: .#filename. The file is deleted when the buffer is saved.
I found a few of these types of temporary files in my Git remote repositories, and I thought it might be better to nip the bud at the source instead of configuring Git to ignore them for every project.
How can we configure Emacs to create those files in the /tmp directory instead of the working directory?

In Java, we can create a temporary file using an existing method known as File.createTempFile () method which creates a new empty file on the specified directory.
The createTempFile () function creates a temporary file in a given directory (if the directory is not mentioned then a default directory is selected), the function generates the filename by using the prefix and suffix passed as the parameters. If the suffix is null then the function uses “.tmp” as suffix. The function then returns the created file
Thank you. Applications can obtain unique file and path names for temporary files by using the GetTempFileName and GetTempPath functions. The GetTempFileName function generates a unique file name, and the GetTempPath function retrieves the path to a directory where temporary files should be created.
The TemporaryFolder Rule allows creating files and folders that are guaranteed to be deleted when the test method finishes (whether it passes or fails). As a conclusion here see some notes regarding the Java File class temporary files:
The file at issue is called a lock file -- commencing with Emacs version 24.3, it can be controlled with the following setting:
(setq create-lockfiles nil)
