Question

i need some help with creating file

Im trying in the last hours to work with RandomAccessFile and try to achieve the next logic:

1. getting a file object
2. creating a temporary file with similar name (how do i make sure the temp file will be created in same place as the given original one?)
3. write to this file
4. replace the original file on the disk with the temporary one (should be in original filename).

I look for a simple code who does that preferring with RandomAccessFile
I just don’t how to solve these few steps right..

Okay so ive attachted this part of code
my problem is that i can’t understand what should be the right steps..
the file isn’t being created and i don’t know how to do that “switch”

        File tempFile = null;
    String[] fileArray = null;
    RandomAccessFile rafTemp = null;
    try {
        fileArray = FileTools.splitFileNameAndExtension(this.file);
        tempFile = File.createTempFile(fileArray[0], "." + fileArray[1],
                this.file); // also tried in the 3rd parameter this.file.getParentFile() still not working.
        rafTemp = new RandomAccessFile(tempFile, "rw");
        rafTemp.writeBytes("temp file content");
        tempFile.renameTo(this.file);
    } catch (IOException ex) {
        ex.printStackTrace();
    } finally {
        rafTemp.close();
    }

you can direct overwrite file. or do following

1. create file in same directory with diff name

2. delete old file

3. rename new file
