I am in the process of making a filereader for listing files and their sizes from a particular directory. All the files that is read is going to be saved in a single textfile!!. Some sort of a combine all files into one big, if you know what i mean :O)


Needed properties:
getAllFilesInDir (and also subdir)
totalSizeOfDir (all files)
fileSize (for a single file)
setSourceDir (path to where filereader is reading)
setDestinationFile (path to store all files read)
numberOfFilesRead
totalKBProcessed

I dont need help with methods, all I want to understand is the classes... superclass, subclass etc...

Could somebody please point me in the right direction??

It doesn't look like object-oriented programming enters at all into your problem. You just input a list of filenames, and output a string.

Why not just declare all functions "static" and stick them in some skeleton class? Just make sure you separate the duties of reading files away from doing the text processing.

BTW, I don't understand why you care about the filesizes, unless you're doing something else you haven't mentioned.

Hope this helps.

If you mean by "output a string" to return a String, that might be a memory problem on a big disk with a lot of files. It probably would be safer to open a stream, run through all the files and dump each to the stream.

By the way, this kind of task would be just a few lines of code in Python or Perl (or even shell script), but will probably be a lot more in Java.
