Reading a line from a file

java-programmer, Reading a line from a file Hi to all, I'm trying to read from a file, line by line, and parse out
the data, by using the line.split(" ") function, and I have a file that
has 8 entries total per line, which means that it supposed to read up
to , array[7], but for some reason, when I run it , it says array
outofboundaries. The only thing here that is to notice, is that the
value at 7 might be either a string or an empty string, can that be a
problem?
Thanks

Try using the trim method of the readLine before using split.

example:

String s = in.readLine.trim();

where in is a BufferedReader

Whoops,

should have been
String s = in.readLine().trim();

Yes: You are using a form of split() that discards
trailing empty strings; see the Javadoc. There's a two-
argument split() method that can be used to retain the
empty trailers; again, see the Javadoc.

yep. an empty line will not be added
