Create a named temp file in Java

Question

I want to be able to create a temporary text File in Java to display on screen, but using File.createTempFile() does not give me enough control over its name.

Any thoughts here?

Answer 1

Why do you need such control over the name of a temporary file?

That question aside, no you can't have full control over the name of the file generated by createTempFile. If you really need full control, you need to create a regular File instead.

You may want to make use of the following:

• java.io.tmpdir System property for temporary file directory
• createNewFile() to check for naming conflicts
• deleteOnExit()
