Reading a file

[Arun Sanker]

Hi Guys,

Iam trying to read a file from a directory as follows:

String name = new String(filePath + fileName + ".apr");
File file = new File(name);

My problem is that the file extension ".apr" could be in any case(For Example:- "apr","APR","Apr")

So my reading of the file fails if the file extension differs from ".apr" to any of the extension I listed above.

So in short when Iam reading a file,would like to ignore the case of the file extension.Cant rely just on the filename ignoring the file extension as there could be files with the same name but different file extension.

Is there any utility method in java to do it or how could it be done....

Thanks

It seems to me if you are using an OS that doesn't distinguish case for the file system, then you wouldn't be having this problem now. Let's assume then that you're running on Linux or Unix or some other real OS. These OSs consider myfile.APR different from myfile.apr, and in fact there could be one of each. Then what would you do?

I would advise checking out the FileFilter interface and implementing a class based on that. You could use the base file name when constructing an instance, then use that instance to get a list of files that match myfile.apr (case insensitive). If you get a list of 0 or 1, you're fine. If you get 2 or more, well then, you've got to have a plan for what to do.
