Reading Last *n* lines from GZIPInputStream

I am reading a huge txt file inside zip.

GZIPInputStream fstream = new GZIPInputStream(new FileInputStream(zipfile));
BufferedReader breader = new BufferedReader(new InputStreamReader(fstream));

I need to read last n lines, of the file.

Is it possible to do that without readline until eof?

Solution

  • Is it possible to do that without readline until eof?

    No and well due to the following two reasons:

    1. You cannot read a stream backwards.
    2. You cannot un(g)zip backwards.

    Just read the entire stream wherein you ignore the lines which you aren't interested in.
