i want to read a text file . that text file is getting updated with every 2 secs by an external program. in fact the text file is a log file of another program. i want to read the log file.i.e reading the last line .

i want to read the last line of the text file whenever i run my java code .

my problem is :

as the log file is updating every 2 secs so how do i read the file ?

i want as soon as i run my file reading code i get the latest last updated line .

How is it possible ?

I could think of two ways:

Most simple, since a living fossil like you definitely will use UNIX, is a /usr/bin/tail.

Else, i think you'll need to bestow the file size somewhere. You could then create an instance of RandomAccessFile, seek() to the last size, and read what has been added, if anything.
