randomaccessfile versus bufferedreader
I want to know which one will be faster randomAccessFil e or Bufferedeader. I am reading a file about 18 MB. For that using randomAccessFil e i will read from the beginning of the file the first time and i will get the position of file pointer depending on the line's data and after that i will start reading from the position of file pointer. this will happen for each call of one method that i wrote..... initially i used BufferedReader but it was slow.....so... -
