How to read partial string from .txt?

in Programming Questions • 2 years ago

Hello,
I am a total beginner in processing, so this really is big problem...
I would like to read lines (one by one) from .txt and send the read information furthes in the patch as a string.
I have figured out how to read the file, but I haven't been succesful in reading just one line per loop and interpreting it as a string... Nor how to read different (following) line each time the loop executes...

Can somebody please help?
Thanks in forward for any advices.

Common solution, when the file isn't too big, is to use loadStrings().
Then you have the whole file in memory, and you can loop over the array of String it returns.
There is a tutorial on arrays in the Learning section if you don't know how to handle them.

Thanks,
well the problem with this is the size of the file - it is somewhere around 600MB...
I will explore the tutorials - I completely forgot that the solution might be there :)

OK, it was the missing information...

In this case, look at the createReader(), example, it should be close of what you want to do.
