    Default Saving the contents of a variable to disk

    I am writing a program that is very computation intensive. I am taking a large number of images, analysing them, and saving the results to an array. This step takes a very long amount of time, especially for large images, so it would be good if there is some way for me to save this array to disk, so I can just reload the variable the next time I run it, instead of starting from scratch.

    I can do this fine with integer arrays, as I just write the numbers into a txt file and reload the next time. But I also have a File[] array, and I don't know how to save this one to disk. Any help? :(

    You cannot write an object array to anything. However, consider providing a unique piece of data (filename is the most obvious--and short filenames have no spaces, you know, PROGRA~1 and all that, so you can still tokenize from spaces), and saving that to the file instead.

    How about saving the full paths to the files to disk. That would allow you to reconstruct the File[] array from the filenames.
