How to read line by line text data from gzipped text file using NIO?

Question

This is my code: (zipped file contains text file)

ByteBuffer buffer = ByteBuffer.allocateDirect(8192);            
try {
      ReadableByteChannel gzc = Channels.newChannel(new GZIPInputStream(Channels.newInputStream( Channels.newChannel( new FileInputStream("C:\\temp\\111.gz")))));

      gzc.read(buffer);                        
}

Answer 1

Performance will also depend on the buffer size. You might want to wrap a BufferedInputStream() into the mix, with a large buffer (eg !MB), to get a lot of blocks from the disk at once.
