hi,
i tried using string tokenizer, but i need to pass the values as float values to the array..The recommendation for StringTokenizer was a mistake. You could use split instead. Or a Scanner.
At any rate so you have some Strings. Which you want to turn into floats.
If only Java had a class, I don't know, let's call it java.lang.Float, and if only such a class existed wouldn't it be just brilliant if it had some sort of method that could parse a float primitive out of a given String?
I mean wouldn't that be just amazing ?
