I have a file with one floating point number per line which I have to
read into an array. I wrote a piece of code using the String Tokenizer
but it tries to tokenize the file name itself instead of the file
contents. I'm VERY new to this so please don't make fun :-P Please help
or at least point in the right direction. Thank you.
