I mean, read ''n write to a file. Actually I''m needing to do it with strings and integers, so isn''t there some other way beside using byte reading? Thanks, Arthur(rockslave)

Check out classes like

- java.io.BufferedReader
- java.io.BufferedWriter
- java.lang.StringBuffer

I think there''s FileReader and FileWriter also.
So basically you open an inputstream to the file you want to read for example, wrap a bufferedreader around it and read the file line by line to stringbuffer. No need to mess with bytes.

Just an idea.

also check out ObjectOutputStream and ObjectInputStream, and interface serializable to go with them. They let you save and load objects directly to and from files.
If you are reading from a file not created by Java then you need to create a filter to change data to byte orientation.

I wanrned you! Didn''t I warn you?! That colored chalk was forged by Lucifer himself!
