Creating a file, read it and discard

I'm getting a file from a HTTP request and I need to read and search for a string. My problem is that the file is not on the system so I need to transferTo a created file.

My question is: where do usually hosts create this temporary files? I want to read the file, search for how many times a string appears and delete the file? Is this the way things are done?

  public static int readTestCaseCode(MultipartFile multipartFile) {
    File file = new File(//Do I need to specify a location?)
    multipartFile.transferTo();
    Scanner scanner = new Scanner(file)
}

Use the static factory method File#createTempFile(String, String) which exactly creates what the name says.

File file = File.createTempFile("myFile", ".exe");

You can also omit the ending and just pass null, which then will be filled with ".tmp", e.g.

File file = File.createTempFile("myFile", null);

The file can then afterwards be deleted by invoking the File#delete() method:

file.delete();
