Thread: Need help on substrings and streams

So i understand the substring method takes the first char position, and then takes in the the length (amount of chars after that initial position). But how would I determine that position if I'm passing in a stream? (the initial position stays the same but the length is always changing)?

How many characters do you want, is what the function is asking for, not how many there are. (If you want "all the characters to the end", then leave it off and that's the default parameter.)

What substring method are you talking about? substr()? How can you pass a stream to the substring method?
