Hi guys. I am new to Java (real new!) and am trying to write a small I/O program. Opening and closing files is not a problem, but what I am haveing trouble with is a) reading a line and then (possibly) manipulating this line using some of the tokenizer functions, and then writing this line to a different file. I am having trouble with how all of this streaming business works! Any ideas?

Do you have to use streams or are you allowed to use Readers/Writers?
If so then you can use FileReader/Writer or (even better) BufferedReader/Writer. The advantage to the buffered one is that it allows you to read lines of text at a time, which you can the tokenize.
Be wary, from memory the readLine may skip blank lines, but I'd have to go check...
