Question

i am trying to read a huge file ( > 1GB) , i am thinking that reading it as a random access file with a buffered reader would be efficient.

i need to read the file line by line and parse it

However being new to JAVA IO Api , i’m not sure how can i do this..

i appreciate your help.

You can use Java’s BufferedReader for this:

BufferedReader reader = new BufferedReader(new FileReader(fileName));
String line;
while ((line = reader.readLine()) != null) {
  // Do some stuff with the line
}

fileName is the path to the file you want to read.
