Hello All!
I am new to Java. I run my java binary from command prompt, where i can run it with a file name, or with the full path of the file(it contains filename in the end). now i want to check whether the argument passed is just a filename or it is the fullpath.if it is the full path(and file name in the end), i want to read the filename from it,
please help me.
thanks

So, if it contains one or more / or \ you've got a full path with maybe a filemane at the end, but you'd still have to check whether 3:/fff/barf/foo.bar/barf is a valid path to a file or just garbage.

Thenks Phein!
but still i did not get how i would be able to do it. and let us suppose that in my case the argument is always a valid path(if it is not a filename).

[PhHein]

You could create a File object from the parameter and use the exists() method to find out whether the file is in your file system. If it is there you've got a valid path to a file.

Thanks!
thanks phein for your reply. but that is what i want. I want to retreive the Filename from the path(if the input argument in a path instid of file)

[PhHein]

Then split the argument, the last token is your file name.

[hakan123]

thanks Phein!
but i wonder if i split my argument, then the last token will be my filename:this will be valid for the case when the argument passed will be a path. my question: if i use split string, will it work in the case when arguemnt is filename???

[PhHein]

Yes it will, why don't you just try it?

[PhHein]

Oh, and another one both these are paths:
c:/foo/doc.doc
c:\foo\doc.doc

args[0].replace("\\","/") will solve that phhein :)

[PhHein]

I know that, but I wanted to give hakan123 a chance to do some research and to learn something new instead of spoon feeding him.
