it's really wired, i have a file of strings, and has methods such as
getString(int), getInt(String)... it worked fine before but today it keeps
throwing this error: java.io.EOFException
at java.io.RandomAccessFile.readInt(RandomAccessFile.java:705)
i didn't change any code of that part, and the file could be read into and
printout well, all the other String works fine, except. one is "persian"...
anyone knows the possible reason?
Thanks!

found the error only happened on the last String of the saved file when using
getString(int no)... still can't finger out yet... //thinking...

Looks like you are trying to use readInt to read a string "persian".
See the javadoc.

no, every string has a id, it should find the string according to the given
id, the id is integer.

using
keeps
and
"persian"...

You'd better provide the piece of readInt(String) code
and the format of your text file, or nobody can help
you out. To me you are trying to read beyond EOF.

thanks! bug corrected! it's the binary search algorithm doesn't work properly,
it read one string length over the end of the file.
Thanks everyone!
goodbug, u r cool!

i read your post it's like you have a property file:
propty file format should be like this
key=value
if it's the file format, using java.util.Properties API will be very easy. If
not then it's different story.

the
"persian".
