    Default Re: Can not rename my File

    i got the answer i am trying renaming the file which has some data in the file.But according to java norms the renameTo() can only rename file which is empty.
    So if i changed System.out.println(cfile.renameTo(abcd)); to System.out.println(bfile.renameTo(abcd)); it will fine...

    What happens instead? And why are you simply throwing that Exception instead of catching it like you should be?
