Method Detail

findNextFile

public static java.io.File findNextFile(java.io.File directory,
                                        java.lang.String filenameFormat)

Returns a File that denotes a file that does not currently exist.

The filename of the file is based on filenameFormat and a number that is calculated by this method. For this algorithm to work, filenameFormat needs to have exactly one occurrence of "%s" in it.

An example of filenameFormat could be "Dayflower-Image-%s.png". This could result in a filename of "Dayflower-Image-1.png". If a file with that filename already exists, the next would be "Dayflower-Image-2.png".

If either directory or filenameFormat are null, a NullPointerException will be thrown.

Parameters:

directory - the directory of the files

filenameFormat - the filename format to use

Returns:

a File that denotes a file that does not currently exist
